amsmathboldboldmathboldsymbol
I am writing a scientific paper with the Springer LaTeX template.
I want to create mathematical symbols in the abstract, such as $10^4$ and $\times$. However, all the equations are shown with bold symbols, as demonstrated below:
How to remove the bold?
You can use the definition style (available though amsthm internally loaded by the class) for your observation theorem-like structure:
\documentclass[a4paper,UKenglish]{lipics}
\theoremstyle{definition}
\newtheorem{observation}[theorem]{Observation}
\begin{document}
\begin{observation}
test
\end{observation}
\end{document}
\mathrm{} is useless in your example.
\documentclass{article}
\usepackage{amsmath} %for \boldsymbol
\begin{document}
Normal Phi: $\Phi$
Bold Phi: $\boldsymbol\Phi$
\end{document}

In the class file
sn-jnl.clsline: 456
\def\Authorfont{\reset@font\fontsize{12bp}{14.5bp}\selectfont\boldmath\titraggedcenter}%This defined macro
\Authorfontwill be used in the macro\artauthorsto type the author field before abstract.\boldmathwill make the author field$^{\dagger}$symbol in bold. However in the definition of\@maketitle, the\artauthorsmacro was not in a group, so it influence the following abstract contents are also in boldmath font. Command patch function frometoolboxpackage,\patchcmd{\@maketitle}{\artauthors}{{\artauthors}}{}{}was used to add the braces around the macro\artauthorsin\@maketitledefenition. In this way, abstract contents won't be influenced by\boldmath.I agree @David's comment. As a journal template, you should leave it and don't use the patch. Or ask springer to fix it.
