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 [tex]A \stackrel{\phi}{\rightarrow} B \stackrel{\psi}{\rightarrow} C[/tex]
I think you can also use \overset{}{} [tex] A \overset{\phi}{\rightarrow} B \overset{\psi}{\rightarrow} C[/tex] Not sure what the difference is.
