How to draw the following symbol in LaTeX?

Question

I want to draw the 'T' like symbol of the following document,

I tried using \mathcal, \mathfrak but it didn't work. I also tried to use detexify but it didn't work.

Can anyone help me?

Answer 1

The glyph you are looking for comes from the Euler script symbols. You can use it by writing in the preamble

\usepackage{eucal}

which redefines \mathcal to provide the Euler script symbols. The original meaning of \mathcal is saved in the macro \CMcal. Alternatively, you can call the package with the option mathscr

\usepackage[mathscr]{eucal}

This leaves \mathcal untouched and provides \mathscr to access the Euler script symbols.

Another alternative (which the documentation seems to consider obsolete) is to call

\usepackage{euscript}

which leaves both \mathcal and \mathscr untouched and simply provides \EuScript.
