LaTeX question

  1. Aug 13, 2008 #1
    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.
