Week of 26 September, 2011 Mathematics Seminars

Seminars for the week of 26 September, 2011

Colloquium

Sept. 29, 2011, 3:30 p.m., in VinH 16

Professor Ovidiu Munteanu
of Columbia University
will speak on
The geometry of gradient Ricci solitons

Abstract: Ricci solitons are natural generalizations of Einstein manifolds. More prominently, they arise in the singularity analysis of the Ricci flow. In this talk, I will survey some recent developments in the study of gradient Ricci solitons. More emphasis will be placed on some interesting information regarding the geometry and topology of Ricci solitons, in arbitrary dimension.
