I am using svjour3
class to draft my manuscript and have many \usepackage
in it. The capital greek letters are rendered italic in the output. svjour3 could be obtained from journal website
Following is a example (the symbols are italic even when no extra packages are loaded)
\documentclass{svjour3}
\usepackage{amsmath}
\begin{document}
This is just the beginning. \\
This is $\Sigma, \Theta$ in italics and I don't want them to be.
\end{document}
How to avoid this? Please do not suggest \usepackage{upgreek}
.
PS: This manuscript I am writing constitutes of abstracts from my thesis, these symbols render correctly in my thesis Latex draft. There would be many other manuscripts and reports simultaneously going on and I want consistency in all. I believe the problem is created by the class file.

The
svjour3
class hasbecause the editorial policy of Springer wants uppercase Greek letters in italics by default.
Use
\mathrm{\Gamma}
and so on if you want them upright. However, you shouldn't be usingsvjour3
for other purposes than submissions to Springer journals.
