<DIV><FONT face=Arial size=2>Title: An inverse function theorem in
C^\infty</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Abstract: We state and prove a "hard" inverse
function theorem which <BR>extends the classical theorem of Nash and Moser. In
contrast with the <BR>latter, we do not use the Newton iteration procedure, so
we do not <BR>require that the function to be inverted is C^2, or even C^1, or
even <BR>Frechet-differentiable. The proof is direct, and relies on Ekeland's
<BR>variational principle. During the colloquium, we will explain the method
<BR>and prove the theorem in the "easy" case (Banach spaces) and
during <BR>the afterwards seminar we will provide the proof in the "hard" case
(Frechet spaces)</FONT></DIV>
