## On the integrability of the geodesic flow on infinite dimensional ellipsoids

Prof. Dr. Jean-Pierre Marco talk

Speaker invited by: Prof. Dr. Thomas Kappeler

**Date:** 13.12.18 **Time:** 15.00 - 16.00 **Room:** Y27H46

In this talk we will first recall the proof of the integrability of the geodesic flow on finite dimensional ellipsoids, together with the necessary underlying algebraic geometry.This will yield a system of first integrals in involution, which we will prove to extend to the case of the infinite dimensional ellipsoids in $\ell^2(\N)$.
