*Mathematisches Kolloquium*

*Prof. Dr. Ivar Ekeland **(**Université Paris-Dauphine**): "A hard 
inverse function theorem"***

**

/_Abstract:_///

/Classically, inverse function theorems are in finite-dimensional 
spaces, or in Banach spaces. It is well known that this framework is 
insufficient in many important cases, for instance when one deals with 
PDEs instead of ODEs. In such cases, one needs an inverse function 
theorem in C^/infty, which is a Fréchet space. Such theorems are called 
"hard" inverse function theorems; the first one is due to John Nash, and 
the method was clarified and extended by Jurgen Moser. There have been 
many variants since then, but all rely on the Newton approximation 
scheme, where the quadratic convergence overcomes the loss of 
derivatives. In this talk, I will review the general framework and 
describe a new result due to Éric Séré, Jacques Fejoz and myself, which 
does not use the Newton method./
