Font used in the book for notation?

[carlosviansi]

Hi,

I was just wondering if anyone would happen to know what is the font used in the book for defining the formulas? say, on Figure 1.2 of page 4, the H, A, g ~~ f ; f: X -> Y and so goes on. I found it pretty nice and would like to use on my written works in LateX if possible as well

Thank you!

Those fonts are the standard latex math fonts. The set notations for X and Y are latex math calligraphic font.

So \mathcal seems to be the key. eg
