hm it does not work...maybe I need to load a special package?
I found that \mathscr makes similar letter but I am not sure if they are the same as gothic (it is called Ralpf Smith's formal script)

On this forum it's working

$$\mathfrak{G} \, \mathfrak{g}$$

The package name to be loaded is <eufrak>.

$$\mathfrak{X}$$
