Scripted letters in papers

  1. Jun 2, 2017 #1
    I was wondering if someone could help me figure out what a scripted letter in a paper I'm reading is called.

    The scripted letter is in equation (3). It looks like some kind of a scripted T.

    It is actually an I, representing the imaginary part, obtained using \Im:
    $$
    \Im \omega_0 \leq \pi T_\mathrm{BH}\, .
    $$

    Arrrgg! MathJax doesn't render that with the right font. Here is how it will look in ##\LaTeX##:

    You can test it in the editor section: type something included in ##\textrm{## \mathfrak{something} ##}## and see what it looks like - ## \mathfrak{something} ## - by the editor function "preview".

    Frequently used fonts are:
    \mathbb{} for double lines as in ##\mathbb{R}##
    \mathcal{} for a look similar to hand writing ##\mathcal{G}##
    \mathfrak{} fraktura for "old" letters like in ##\mathfrak{su}(2)##

    Here's an overview of LaTeX symbols: http://detexify.kirelabs.org/symbols.html
