Replacing Notation with Function Names: Possible?

[dans595]

I have something like


A \rightarrow B \rightarrow C


I'd like to put function name's about the \rightarrow's, to replace the notation


\phi : A \rightarrow B, \psi : B \rightarrow C.


Is this possible? Thanks!

You can use \stackrel{}{}.

A \stackrel{\phi}{\rightarrow} B \stackrel{\psi}{\rightarrow} C

gives

$$A \stackrel{\phi}{\rightarrow} B \stackrel{\psi}{\rightarrow} C$$

You can use \stackrel{}{}.

A \stackrel{\phi}{\rightarrow} B \stackrel{\psi}{\rightarrow} C

gives

$$A \stackrel{\phi}{\rightarrow} B \stackrel{\psi}{\rightarrow} C$$

I think you can also use \overset{}{}

$$A \overset{\phi}{\rightarrow} B \overset{\psi}{\rightarrow} C$$

Not sure what the difference is.
