Title:
"3-manifolds under an integral pinching assumption are space form"

Wed. 11 July 2007  @  02.30 p.m.

SISSA - Main Building - ground floor - room B

Abstract : we will show that a 3-manifold with positive scalar curvature and 
satisfying an integral pinching assumption beetwen the $L^2$-norm of the Ricci 
curvature and the $L^2$-norm of the scalar curvature is a spherical space form 
(ie admits an Einstein metric with positive curvature). This will be done by 
solving a fully non linear differential equation.
