I already tried to use Detexify but the closest suggestion was \mathfrak{Y}. I'm sure that it is not the case.

Does anybody have idea how to produce the letter used for the space cited on the image?

It certainly looks like a \mathfrak{Y}, for instance from esstix fonts (see mathalfa).

You can as well use the yfonts package, following @egreg's answer here.

\documentclass{article}
\usepackage{yfonts}
\begin{document}
    \textfrak{Y}
\end{document}
