Hello again, I read and have applied what it is explained here:

https://orgmode.org/manual/Working-with-LaTeX-math-snippets.html#FOOT136

It works rather well, but for some symbols it does not work : for example
for \(\bot\)  the code for falsity constant in  LaTeX, it does not work.

I imagine that I have not installed some library?
