\begin{abstract}
  This bundle provides OpenType versions of Type1 Kp-fonts designed by
  Christophe Caignaert. See \file{Kpfonts-Doc-English.pdf} for the  full
  documentation of the original Type1 fonts.

  It is usable only with LuaTeX or XeTeX engines; it consists of sixteen Text
  OpenType fonts, a Roman family \family{KpRoman} in eight shapes and weights
  ---\famvar{Regular}, \famvar{Italic}, \famvar{Bold},
  \famvar{Bold\-Italic}, \famvar{Light}, \famvar{Light\-Italic},
  \famvar{Semi\-bold}, \famvar{Semibold\-Italic}---, a Sans-Serif family
  \family{KpSans} and a TypeWriter family \family{KpMono}, each of them
  in four shapes and weights---\famvar{Regular}, \famvar{Italic},
  \famvar{Bold} and \famvar{Bold\-Italic}--- and six maths OpenType fonts
  \family{KpMath-Regular}, \family{KpMath-Bold}, \family{KpMath-Light},
  \family{KpMath-Semibold}, \family{KpMath-Sans} and \family{KpMath-SansBold}.

  \family{KpRoman} and \family{KpSans} families have small caps available in
  two sizes (SmallCaps and PetiteCaps), upper and lowercase digits
  ({\addfontfeatures{Numbers=Lowercase} 0123456789}), ancient ligatures
  {\addfontfeatures{Ligatures=Rare} ct, st} and
  {\addfontfeatures{Style=Swash}Q} a long-tailed capital Q.
  Superior and inferior digits and letters have been added to the OpenType
  \family{KpRoman} and \family{KpSans} fonts for footnotes’ calls and
  abbreviations 1\textsuperscript{st}, 2\textsuperscript{nd}…

  The support of text fonts covers Latin and Latin Extended~A (U+0020 to U+017F)
  but neither IPA nor Greek nor Cyrillic alphabets.

  For all maths fonts, Latin and Greek letters are available in Upright and
  Italic shapes, in Bold and Regular weights:
  $\symup{a}$ $\symup{\beta}$ $\symup{C}$ $\symup{\Delta}$,
  $\symit{a}$ $\symit{\beta}$ $\symit{C}$ $\symit{\Delta}$,
  $\symbfup{a}$ $\symbfup{\beta}$ $\symbfup{C}$ $\symbfup{\Delta}$,
  $\symbfit{a}$ $\symbfit{\beta}$ $\symbfit{C}$ $\symbfit{\Delta}$.

%  Blackboard Bold capitals are available in two shapes, Serif and Sans:
%  |\mathbb{ABC}| prints either
%  \mathversion{full}$\mathbb{ABC}$ (option |[Style=bbsans]|) or
%  \mathversion{base} $\mathbb{ABC}$ (default).
  Blackboard Bold capitals are available in two shapes, Serif and Sans:
  |\mathbb{ABC}| prints either
  \mathversion{base} $\mathbb{ABC}$ (default) or
  \mathversion{full}$\mathbb{ABC}$ (option |[Style=bbsans]|)
  Commands |\mathcal{ABC}| and |\mathscr{ABC}| print respectively
  \mathversion{full}$\mathcal{ABC}$ and \mathversion{base}$\mathscr{ABC}$
  while |\mathfrak{ABCabc}| prints $\mathfrak{ABCabc}$.

  File \file{unimath-kpfonts.pdf} shows the full list of Unicode maths symbols
  provided by Kp-fonts, compared with other common maths fonts.
  More symbols, specific to Kp-fonts, are listed in
  section~\ref{ssec:symb-spec-kp}.

  A style file \file{kpfont-otf.sty} is provided to load Kp-fonts easily.
  It is derived from \file{kpfont.sty} but options differ.

  Please beware of the \emph{experimental} status of the current
  version~(\version).

  All fonts are covered by OFL licence, style file and documentation
  are under LPPL-1.3 licence.

\section{Loading \pkg{kpfonts-otf.sty}}

For users of the original \pkg{kpfonts.sty} package, the easiest way to
try the OpenType version is to load \pkg{kpfonts-otf.sty}:\\[.5\baselineskip]
|\usepackage[ |\optit{options}| ]{kpfonts-otf}|\\[.5\baselineskip]
this loads \pkg{unicode-math}, \pkg{fontspec} and \pkg{realscripts}, and defines
\family{KpRoman} (\family{Regular} or \family{Light} depending on options),
\family{KpSans} and \family{KpMono} as Text fonts, \family{KpMath}
(\family{Regular} or \family{Light} depending on options) as maths fonts.

\pkg{kpfonts-otf.sty} also defines all symbols available in \pkg{latexsym} and
\pkg{amssymb} under the same names%
\footnote{Unicode names often differ from AMS names.}
and a bunch of Kp-fonts specifics symbols.

\subsection{Global options for both text and maths}

\begin{description}
\item[light:] switches to \famvar{light} fonts, metrics are unchanged;
  \famvar{light} fonts might not look perfect on screen but they print fine.

  Please compare \famvar{regular} (left) and \famvar{light} fonts (right):

\newcommand*{\test}{Normal or light? Just a matter of taste}

\medskip
\begin{minipage}{.45\textwidth}\test. $E=mc^2$\end{minipage}\hfill
\begin{minipage}{.45\textwidth}\ltseries\test. \mathversion{light}$E=mc^2$
\end{minipage}

\medskip\mathversion{base}
\begin{minipage}{.45\textwidth}\itshape \test\end{minipage}\hfill
\begin{minipage}{.45\textwidth}\ltseries\itshape\test\end{minipage}

\medskip
\begin{minipage}{.45\textwidth}\bfseries \test\end{minipage}\hfill
\begin{minipage}{.45\textwidth}\sbseries \test\end{minipage}

\medskip
\begin{minipage}{.45\textwidth}\bfseries\itshape \test\end{minipage}\hfill
\begin{minipage}{.45\textwidth}\sbseries\itshape\test\end{minipage}

\medskip
\item[sans:] switches to \famvar{sans-serif} fonts for text and maths.

\item[nomath:] load neither \pkg{unicode-math} nor \family{KpMath} fonts;
  useful for documents without maths, or to choose other maths fonts.
\item[notext:] do not change any Text font, use the defaults.
\item[nosf:]   do not change Sans-Serif Text fonts, use the defaults.
\item[nott:]   do not change Typewriter Text fonts, use the defaults.
\item[onlyrm:] equivalent to the last two combined.
\item[fulloldstyle:] equivalent to options \opt{oldstyle} and
  \opt{oldstylemath}.
\item[fulloldstylenums:] equivalent to options \opt{oldstylenums} and
  \opt{oldstylenumsmath}.
\end{description}

\subsection{Options for text fonts \emph{only}}

\begin{description}
\item[lighttext:] switches to \famvar{light} Text fonts.

  Two more weights are provided by \pkg{kpfonts-otf.sty}:
  with the \famvar{lighttext} (or \famvar{light}) option, \famvar{Semibold} and
  \famvar{Extrabold} vs \famvar{Light} and \famvar{Semibold} without it.
  These weights are available through |\ltseries|, |\sbseries| and
  |\ebseries| commands to be used in a group or alternatively through one
  argument commands |\textlt{}|,   |\textsb{}| and |\texteb{}|.

  |{\sbseries\itshape Foo}| or |\textsb{\textit{Foo}}| print
  {\sbseries\itshape Foo}.

\item[sfstext:] switches to \famvar{sans-serif} text fonts.

\item[oldstylenums:] provides lowercase digits as a default.

  To get uppercase digits locally: |{\addfontfeature{Numbers=Lining} 123}|.

  Examples, upright, italic, bold and bolditalic:
  \begin{itemize}\addfontfeatures{Numbers=Lowercase}
	\item 0123456789 !
	\item \textit{0123456789 !}
	\item \textbf{0123456789 !}
	\item \textbf{\textit{0123456789 !}}
  \end{itemize}

\item[oldstyle:] provides lowercase digits as a default, long-tailed Q
  ({\addfontfeatures{Style=Swash}Quebec}) and (for Roman and Sans-Serif
  fonts only) old style ligatures
  {\addfontfeatures{Ligatures=Rare}`ct’ and `st’}.

  Examples:
  \begin{itemize}\addfontfeatures{Style=Swash,Ligatures=Rare}
  \newcommand*{\test}{Quest for an attractive font!}
	\item \test
	\item \textit{\test}
	\item \textbf{\test}
	\item \textsc{\test}
	\item \textbf{\textit{\test}}
	\item \textsc{\textbf{\test}}
  \end{itemize}

\item[veryoldstyle:]\hlabel{veryoldstyle} same as option \opt{oldstyle} but
  the round `s’  is replaced by the long one `ſ’
  unless it ends a word or is followed by \textit{b}, \textit{f} or \textit{h}%
  \footnote{Rules found on
    \href{https://fr.wikipedia.org/wiki/S_long}{wikipedia}.}
  and ancient ligatures {\addfontfeatures{RawFeature=+hist;+hlig} si, sl, st}
  are activated.
  Coding |\textit{some of Highlands’ mysterious castles…}| will print
  {\addfontfeatures{RawFeature=+hist;+hlig;+calt}%
    \textit{some of Highlands’ mysterious castles…}} which is correct.

  The automatic substitution relies on the OpenType feature
  \texttt{StylisticSet=12}.  A round `s’ (resp. long `ſ’) can be forced by
  coding \texttt{s\char"200B=} or |\shorts{}| (resp. \texttt{ſ}%
  \footnote{On Unix systems the \texttt{Compose} key can be used:
    \texttt{Compose f s}.}
  or |\longs{}|).

\item[largesmallcaps:] prints larger \textlsc{Small Caps} than the default
  ones (\textsc{Petite Caps}).

\item[altfligs :] prints alternative shapes for ligatures
  {\addfontfeatures{StylisticSet=1}fi, fl, ffi, ffl}
  instead of fi, fl, ffi, ffl.

\item[germandbls :] |\SS| prints {\addfontfeatures{StylisticSet=2}\SS} instead
  of {\char"1E9E} (capital \textit{Eszett}), ditto for small/petite caps.

\item[eurosym :] replaces the Euro character (€) by the official symbol
  {\addfontfeatures{StylisticSet=3}(€)} (available in regular, italic,
  bold and bolditalic).
  %; the |\KPeuro| command is also provided to print
  %the official symbol, it accepts an optionnal argument : |\kpeuro[1,50]{}|
  %prints \kpeuro[1,50] (with a nobreak space).

\item[harfbuzz :] switches |Renderer=Harfbuzz| for HBLuaTeX engine;
  up to version 0.34, this renderer was silently activated but seldom useful.

\end{description}

\subsection{Options for maths fonts \emph{only}}

\begin{description}

\item[lightmath:] uses \famvar{light} maths fonts.

\item[sfmath:] uses \famvar{sans-serif} maths fonts.

\item[bbsans:] command |\mathbb| prints Sans-Serif Blackboard Bold capitals
  with Serif fonts too: compare
  \mathversion{full}
  $\mathbb{C}$, $\mathbb{K}$, $\mathbb{N}$, $\mathbb{Q}$, $\mathbb{R}$,
  $\mathbb{Z}$, with
  \mathversion{base}
  $\mathbb{C}$, $\mathbb{K}$, $\mathbb{N}$, $\mathbb{Q}$, $\mathbb{R}$,
  $\mathbb{Z}$ (default).

%\item[mathcal:] forces commands |\mathcal| and |\mathscr| to print
%  \mathversion{full}$\mathcal{A,B,C,D}$  % $\mathscr{ABCD}$
%  instead of \mathversion{base} $\mathcal{A,B,C,D}$ (default).

\item[frenchstyle:] Latin uppercase letters and all Greek letters are
  printed upright, only lowercase Latin letters are printed in italics;
  this follows the French typographic usage.

\item[oldstylenumsmath:] prints lowercase digits in maths (default is
  uppercase).

\item[narrowiints:] prints condensed repeated integrals :

  \mathversion{full}$\iiint$ and $\displaystyle\iiint$
  \quad instead of \quad
  \mathversion{base}$\iiint$ and $\displaystyle\iiint$ (default).

\item[partialup:] the |\partial| symbol is printed upright $\symup{\partial}$
  instead of $\partial$.

\item[fancyReIm:] commands |\Re| and |\Im| print $\RE$ and $\IM$ respectively
  instead of $\Re$ and $\Im$.

\item[tight :] horizontal spaces tightened in maths mode (same settings as
  \pkg{fourier-otf}).

\item[noDcommand:] do not define |\D| to avoid incompatibilities with other
  packages.

\end{description}

Please note that the \textsf{\textbf{mathcal}} option has been
deleted: commands |$\mathcal{ABC}$| and |$\mathscr{ABC}$| now print
\mathversion{full}$\mathcal{ABC}$ and \mathversion{base}$\mathcal{ABC}$
respectively when \pkg{kpfonts-otf.sty} is loaded.

\section{Another way to load Kp-fonts}
\label{sec:options-standard}

Loading Kp-fonts through \file{kpfonts-otf.sty} offers only a limited choice
of options; the standard commands \cmd{setmainfont}, \cmd{setsansfont},
\cmd{setmonofont}, \cmd{setmathfont} offer much more flexibility.

On the other hand, \file{kpfonts-otf.sty} defines a lot of useful commands
to access AMS and specific Kp-fonts symbols. Loading \pkg{kpfonts-otf} with
the \opt{symbols} option enables to get all these commands defined without
loading any font:
\begin{verbatim}
\usepackage[symbols]{kpfonts-otf}
\end{verbatim}
Please note that \pkg{unicode-math}%
\footnote{A careful reading of both manuals \file{unicode-math.pdf} and
  \file{fonspec.pdf} (available in all TeX distributions) is required in
  order to take full advantage of these packages.}
(and \pkg{fontspec}) \emph{are loaded} by this procedure, no need to do it
again, unless specific options are required, then \pkg{unicode-math} has to be
loaded \emph{before} \pkg{kpfonts-otf}, f.i.:
\begin{verbatim}
\usepackage[math-style=ISO,bold-style=upright]{unicode-math}
\usepackage[symbols]{kpfonts-otf}
\end{verbatim}
Then, it is up to the user to load Kp-fonts with whatever option he/she likes
using commands\\[.5\baselineskip]
|\set...font{|\optit{font}|}[|\optit{options}|]|.

For documents requiring no maths fonts, loading \pkg{fontspec} and using
the |\set...font| commands is enough, no need to load \pkg{kpfonts-otf} at all.

\subsection{Options for Text fonts}

Here are the options available for Text Kp-fonts:
\begin{description}
\item[Numbers=Lowercase] to get lowercase digits
  {\addfontfeature{Numbers=Lowercase} 1,2,3} instead of 1,2,3;
  the default is\\   \style{Numbers=Lining}.

\item[SmallCapsFeatures = \{Letters=SmallCaps\}] the |\textsc{}| command
  will print larger \textlsc{Small Caps} than the default
  \textpsc{Petite Caps}.\\
  The default setting%
  \footnote{Changed in v0.37 to match the original \pkg{kpfonts} package.},
  is \style{SmallCapsFeatures = \{Letters=PetiteCaps\}}.

\item[Ligatures=TeX]  (default) |'|\quad|!`|\quad|?`|\quad|--|\quad |---|\quad
  print respectively\quad ’ \quad !` \quad ?`\quad -- \quad ---.

\item[Ligatures=Common] (default) automatic ligatures  ff ffi ffl fi fl
  (plus s\char"200B=).

\item[StylisticSet=1] provides an alternative for glyphs
  {\addfontfeature{StylisticSet=1} ffi ffl fi fl} (ff is unchanged).

\item[Ligatures=Required :] adds {\addfontfeature{Ligatures=Required} ft and tt}
  ligatures.

\item[Ligatures=Rare] adds {\addfontfeature{Ligatures=Rare} ct and st} ligatures.

\item[Style=Swash] to get the long-tailed capital
  Q: {\addfontfeature{Style=Swash}Queen, also in small caps (both sizes):
    \textpsc{Queen} and \textlsc{Queen}}.

\item[Style=Historic] replaces any instance of `s’ by the long variant~`ſ’.
  It is still possible to get a round `s’ coding it as
  `\texttt{s\char"200B=}’; this option should no longer be used, it is
  superseded by \opt{StylisticSet=12} below.

\item[StylisticSet=12] has been described in option \opt{veryoldstyle}
  p.~\pageref{veryoldstyle}: it operates a contextual substitution of
  round~`s’ by long~`ſ’. An alias \opt{Style=autolongs} is available if
  \pkg{kpfonts-otf.sty} has been loaded.

\item[Ligatures=Historic] switches specific ligatures for the long~ſ:
   {\addfontfeature{Style=Historic,Ligatures=Historic} si, sl, st}.

\item[StylisticSet=2 :] |\SS| prints {\addfontfeatures{StylisticSet=2}\SS}
  instead of {\char"1E9E} (capital \textit{Eszett}), ditto for small/petite caps.

\item[StylisticSet=3] replaces the Euro character (€) by the official symbol
  {\addfontfeatures{StylisticSet=3}(€)} (available in regular, italics,
  bold and bolditalic).

\end{description}

Options may be are chosen for each font, say:
\begin{verbatim}
\setmonofont{KpMono}[Numbers=Lowercase,Style=Historic]
\end{verbatim}
but can also be shared by different typefaces:
\begin{verbatim}
\defaultfontfeatures+[KpRoman,KpSans,KpMono]{Numbers=Lowercase}
\defaultfontfeatures+[KpRoman,KpSans]{%
  Ligatures = Rare,
  Style = Swash,
  SmallCapsFeatures = {Letters=PetiteCaps},
  }
\setmainfont{KpRoman}
\setsansfont{KpSans}
\setmonofont{KpMono}
\end{verbatim}
Notes : 1. |\setmonofont{KpMono}|, |\setsansfont{KpSans}|,
|\setmainfont{KpRoman}| rely on files \file{KpMono.fontspec},
\file{KpSans.fontspec} and \file{KpRoman.fontspec} installed by Kpfonts.

2. Note the |+| ending |\defaultfontfeatures+| : options are \emph{added},
not overwriting any other (including those of \file{fontspec.cfg}).

3. Options can be gathered: |Ligatures={Rare,Historic}| (with braces)
is equivalent to |Ligatures=Rare| and |Ligatures=Historic|.

4. These options can also be switched on and off \emph{locally}
using |\addfontfeatures| inside a group, f.i.\ to print lowercase digits
{\addfontfeatures{Numbers=Lowercase}1234576890} with a font loaded with option
|Numbers=Lining|:
\begin{verbatim}
{\addfontfeatures{Numbers=Lowercase}1234576890}
\end{verbatim}
Actually, a shortcut is available in this case: |\oldstylenums{1234576890}|.

5. With the \family{KpRoman}, it is possible to define two more weights
\famvar{Light} and \famvar{Semibold} borrowed from \family{KpLight}:
\begin{verbatim}
\newfontfamily\KpLight{KpLight}[<same options as KpRoman>]
\newcommand*{\ltseries}{\KpLight}
\newcommand*{\sbseries}{\KpLight\bfseries}
\DeclareTextFontCommand{\textlt}{\ltseries}
\DeclareTextFontCommand{\textsb}{\sbseries}
\end{verbatim}
  These weights are then available through |\ltseries|, |\sbseries| commands
  to be used in a group or alternatively through one argument commands
  |\textlt{}| and  |\textsb{}|.

  With the \family{KpLight}, weights \famvar{Semibold} and \famvar{Extrabold}
  can be defined similarly.

\subsection{Options for maths fonts}

The following options can be passed either to \pkg{unicode-math}%
\footnote{See the manual \file{unicode-math.pdf}.}
or to |\setmathfont{}|:
\begin{description}
\item[math-style =] \opt{ISO}, \opt{TeX} (default), \opt{french}, \opt{upright};
\item[bold-style =] \opt{ISO}, \opt{TeX} (default), \opt{upright};
\item[partial =] \opt{upright} (default italic);
\item[nabla =]  \opt{italic}  (default upright);
\end{description}

Seven `Style Variants’ are available with Kp-fonts, here are the first three:
\begin{description}
\item[Style=mathcal] (\texttt{+ss01}) commands |\mathcal{}| and |\mathscr{}|
  print \mathversion{full}$\mathcal{ABC}$ instead of
  \mathversion{base}$\mathcal{ABC}$ (default), see note below;

\item[Style=bbsans] (\texttt{+ss02}) |\mathbb{}| prints Sans-Serif
  Blackboard bold capitals \mathversion{full}$\mathbb{ABC}$ for Serif maths fonts
  \file{KpMath-Regular} and \file{KpMath-light} instead of
  \mathversion{base}$\mathbb{ABC}$ ;

\item[Style=narrowiints] (\texttt{+ss03}) provides condensed repeated integrals:
  \mathversion{full}$\iiint$ instead of
  \mathversion{base}$\iiint$ (default).
\end{description}

\textbf{Note:} if you want commands |$\mathcal{ABC}$| and |$\mathscr{ABC}$| to
print \mathversion{full}$\mathcal{ABC}$ and \mathversion{base}$\mathcal{ABC}$
respectively, you can use \pkg{unicode-math}’s option |range| this way:\\
|\setmathfont{KpMath-Regular}[|\optit{options}|]|\\
|\setmathfont{KpMath-Regular}[range={cal,bfcal},StylisticSet=1]|\\
Both lines are mandatory: the first one loads \family{KpMath} as usual while
the second one modifies |\mathcal{}| command’s output.

Example: switching styles 4 (leqslant) and 6 (subsetneq) can be achieved
coding either\\
|\setmathfont{KpMath-Regular.otf}[StylisticSet={4,6}]|\quad or\\
|\setmathfont{KpMath-Regular.otf}[Style={leqslant,subsetneq}]|\\
but this second syntax is available only if \pkg{kpfonts-otf.sty} has been
loaded (eventually with the \opt{symbols} option).

\vspace{\baselineskip}
Example: with |\setmathfont{KpMath-Regular.otf}[CharacterVariant={3,6}]|\\
commands |\epsilon| and |\phi| print $\varepsilon$
and $\varphi$ instead of $\epsilon$ and $\phi$.
The same is true of course for all shapes and and weights (upright, bold,
bolditalic, sans-derif, etc.): f.i.\ with \opt{math-syle=french}, |\epsilon|
and |\phi| print $\symup{\varepsilon}$ and $\symup{\varphi}$ (upright).

Note about \cmd{hbar}: \pkg{unicode-math} defines \cmd{hbar} as
\cmd{hslash} (U+210F) while \pkg{amsmath} provides two different glyphs
(italic h with horizontal or diagonal stroke).\\
\pkg{kpfonts-otf} now follows \pkg{unicode-math}; the italic h with horizontal
stroke can be printed using \cmd{hslash} or \cmd{hbar} together with character
variant \texttt{cv01} or with \cmd{mithbar} (replacement for AMS’ command
\cmd{hbar}).

\section{Specific commands defined in \pkg{kpfonts-otf.sty}}

\subsection{Integrals}

Kp-fonts offers variants for integral symbols suitable for indefinite
integrals, they are coded as |\varint|, |\variint|, |\variiint|, |\variiiint|
and |\varidotsint|.  Compare $\int f(t)\,dt$ and $\varint f(t)\,dt$ and also

\[\int f(t)\,dt \qquad\text{and}\qquad\varint f(t)\,dt\]

|\D{...}| prints an upright `d’ and improves kernings around the differential
element:
|\displaystyle\varint f(t)\D{t}| prints	$\displaystyle\varint f(t)\D{t}$.

\subsection{Maths Versions}

Different versions of the \family{KpMath} fonts may be defined in the
document’s preamble:\\
|\setmathfont{KpMath-Regular.otf}[version=base|, \optit{options} |]|\\
|\setmathfont{KpMath-Bold.otf}[version=bold|, \optit{options} |]|\\
|\setmathfont{KpMath-Semibold.otf}[version=semibold|, \optit{options} |]|\\
|\setmathfont{KpMath-Sans.otf}[version=sans|, \optit{options} |]|\\
|\setmathfont{KpMath-Light.otf}[version=light|, \optit{options} |]|\\
then, it is easy to switch from one version to another one with
|\mathversion{|\optit{name}|}|.

\pagebreak[4]
Example\footnote{\mathversion{full}Option \opt{CharacterVariant=3} changes
$\epsilon$ into $\varepsilon$.} :
\begin{verbatim}
\setmathfont{KpMath-Regular.otf}[Style=leqslant, CharacterVariant=3]
\setmathfont{KpMath-Bold.otf}[version=bold,
                              Style=leqslant, CharacterVariant=3]
\setmathfont{KpMath-Sans.otf}[version=sans,
                              Style=leqslant, CharacterVariant=3]
\end{verbatim}

Here is the same equation in three versions, normal, bold and Sans-Serif:
\mathversion{base}

\[ \mathbb{E}_i(N_i) = \sum_{n\ge1} P_i(N_i\ge n)
                     = \frac{\epsilon_i}{1-\epsilon_i}<+\infty \]

|\mathversion{bold}| \mathversion{bold}
\[ \mathbb{E}_i(N_i) = \sum_{n\ge1} P_i(N_i\ge n)
                     = \frac{\epsilon_i}{1-\epsilon_i}<+\infty \]

|\mathversion{sans}| \mathversion{sans}
\[ \mathbb{E}_i(N_i) = \sum_{n\ge1} P_i(N_i\ge n)
                     = \frac{\epsilon_i}{1-\epsilon_i}<+\infty \]
