Lundi 23 mai 2011 16:00-17:00 - Albin Pierre - Courant Institute et Jussieu

Résumé : The signature operator of a Riemannian metric is animportant tool for studying topological questions with analyticmachinery. Though well-understood for smooth metrics oncompact manifolds, there are many open questions when themetric is allowed to have singularities. I will report on joint workwith Eric Leichtnam, Rafe Mazzeo, and Paolo Piazza on thesignature operator on stratified pseudomanifolds and some ofits topological applications.
