I'm writing my thesis using a custom document class provided by our university vutinfth ( template in overleaf ), the title of the thesis has a few math symbols, which I need them to be bold to match the Title, however when I use \mathbf (in fact any \math... command) I get the error ! Undefined control sequence. And instead of the title: edefYou'reintroublehere.Trytyping<return .....

Unfortunately I'm not equipped to debug this issue, so I would appreciate any help on how I can debug, hack, or figure out a workaround.

here's what I found so far. To set the title of the thesis we use \settitle{}{}, to set an English and a German title, and which is defined as follows:

\newcommand{\settitle}[2]{%
 \CreatePolylingual[english=#1,naustrian=#2]{Title}%
}%

such that CreatePolylingual is:

\newcommand{\CreatePolylingual}[2][]{%
\begingroup
 \setkeys{vutinfth}{#1}%
 \vutinfth@allocate@polylingual{#2}%
\endgroup
\@namedef{vutinfth@polylingual@#2}{%
 \vutinfth@selectlanguage@polylingual{#2}}%
}%

Interesting question! Following the chain of commands for a few more levels, the \settitle command ends up defining the names \vutinfth@Title@english for the English title and \vutinfth@Title@naustrian for the German title. There’s a bug that makes this break if you use commands inside the title, but rather than attempt to patch this command, we can just fix it up right after:

\settitle{Incorrect Title}{Incorrect Title} % Sets English and German version of the title (both can be English or German).
\makeatletter
\def\vutinfth@Title@english{\boldmath Why Does the Universe use \(\mathbb{R}^3\)?}
\def\vutinfth@Title@naustrian{\boldmath Why Does the Universe use \(\mathbb{R}^3\)?}
\makeatother

This thesis class does not provide any way to override the formatting of the title other than to insert a new command within it, so I add \boldmath to select the bold version of all math symbols. (One gotcha that might or might not be relevant: for bold symbols such as vectors within bold math, with the bm package, you might need to use \hm{v}.) We need the \makeatletter for LaTeX to accept csnames containing @ in a .tex file. You can write your title in German better than I could, so I’ll spare you any attempt.

We’re not done yet. Earlier up in the preamble, the template calls \hypersetup and sets pdftitle to \thesistitle, which was defined as a placeholder. This needs to be Unicode, not TeX, so we can change this one line to:

pdftitle        = {Why does the Universe Use ℝ³?},         % The document's title in the document properties (optional).

You will need to choose the best approximation to the title you want that you can, without switching to math mode.

Finally, you need to add bold versions of the math-mode symbols you use, so add to the list of packages in the preamble:

\usepackage{bm}  % Improves the appearance of \boldmath and \boldsymbol.
\usepackage[bb=px]{mathalpha}  % A free \mathbb alphabet with a bold version.

You could stick them right before \usepackage{hyperref} if you don’t want the comment about how that has to be second-to-last to go out of date.

Here is a complete version of example.tex from the Overleaf template:
