Hello MHB.
Suppose I have a function $f:X\to Y$ which sends $a$ to $b$.
I want to express this as:
Consider a function $\frac{f:X\to Y}{a\xrightarrow{h}b}$.
OR
Consider a function $\frac{f:X\to Y}{f:a\mapsto b}$.
Only thing, I don't want the 'horizontal bar' which separates $f:X\to Y$ from $a\xrightarrow{h}b$ (or $f:a\mapsto b$).
Does anybody know how to do this?
Also, is there a way to write $h$ on top of $\mapsto$ just as I can right $h$ on top of $\rightarrow$?
