I am writing a document with too many long equations and I adopted the use of breqn
package for its simplicity in writing such long equations when alignment is not a big restriction. The problem is when I use newtxmath
I can not get correct Greek math capitals. If I use Computer Modern, the problem disappears.
Here is my MWE which shows the problem:
\documentclass[a4paper,oneside,12pt]{book}
\usepackage{lmodern}
\usepackage{newtxtext}
\usepackage[scaled=0.92]{helvet}
\usepackage{textcomp}
\usepackage{amsmath}
\usepackage[cmintegrals,bigdelims]{newtxmath}
%\usepackage{flexisym}
%\usepackage{breqn}
\usepackage{bm} % load after all math to give access to bold math
\begin{document}
Some alternative text goes here.

\begin{equation}\label{eqdsb}
\varphi^{}_{\mathrm{DSB-SC}}(t)\ne\Delta\varphi^{}_R\ne\Delta\theta^{}_R
\end{equation}
%\begin{dmath}
%I_{3} =
%%
%\sum_{k=1}^{\infty}{\frac{\left(\frac{c}{\bar{\gamma}\pi ^{\frac{3}{2}}}\right)(-1)^{k+1}\left (\frac{K}{\sqrt{a_{10}}}\right )^{2k-1}\Gamma \left (p+\frac{1}{2}\right )}{(2k-1)(k-1)!\Gamma (p+1)}}\left \{E_{4k-2}\left (\frac{1}{\bar{\gamma }}\right )\delta (p)+\frac{1}{2\bar{\gamma}\sqrt{\pi}} \right . \times
%%
%\sum_{p=1}^{\infty}\left(\frac{(-1)^{p}(2k-1)(2k-3)\ldots (2k-(2p-3))}{2^{p}p!} \right . \times
%%
%\left.\left. \frac {b^{p}\Gamma(p+\frac{1}{2})}{\Gamma(p+1)} E_{4k-2}\left (\frac{1}{\bar{\gamma}}\right )\right )\right \}.
%\end{dmath}
\begin{equation}
\begin{split}
I_{3} &= \\
%
&\sum_{k=1}^{\infty}{\frac{\left(\frac{c}{\bar{\gamma}\pi ^{\frac{3}{2}}}\right)(-1)^{k+1}\left (\frac{K}{\sqrt{a_{10}}}\right )^{2k-1}\Gamma \left (p+\frac{1}{2}\right )}{(2k-1)(k-1)!\Gamma (p+1)}}\left \{E_{4k-2}\left (\frac{1}{\bar{\gamma }}\right )\delta (p)+\frac{1}{2\bar{\gamma}\sqrt{\pi}} \right . \times\\
%
&\sum_{p=1}^{\infty}\left(\frac{(-1)^{p}(2k-1)(2k-3)\ldots (2k-(2p-3))}{2^{p}p!} \right . \times \\
%
&\left.\left. \frac {b^{p}\Gamma(p+\frac{1}{2})}{\Gamma(p+1)} E_{4k-2}\left (\frac{1}{\bar{\gamma}}\right )\right )\right \}.
\end{split}
\end{equation}
\end{document}
I commented out the problematic parts. The desired output should be like this:
If I uncomment the commented lines, I get Gamma
as \prime
symbol. I appreciate your help.
breqn
makes some default assumptions about the font slots where characters and symbols are taken from, which fail in case some packages are loaded, which differ from the standard setup (note thatnewtxmath
has good reasons for doing this).
