### On modular forms of characteristic p>0, by Marc Reversat

We compare modular forms of characteristic $p>0$
(i.e. Drinfeld's modular forms) and automorphic forms.
We prove that spaces of these modular forms (which are of
characteristic $p$) can be described by function spaces of
characteristic zero, close to those of automorphic forms.
