Speaker: Dr. Zhou Zhang (University of Sydney) Title: Introduction to Ricci flow Date: Friday, 19 November, 2010 Time: 14:00 Venue: Room OMB 145, Old Main Building, UNSW Introduction to Ricci flow Abstract: In this expository talk aiming at general audience, we begin with some basic facts regarding the Ricci flow and its complex version, the Kähler-Ricci flow. Then we look into a few very natural questions that people might ask when coming across these objects for the first time. In fact, after the invention of the Ricci flow by R. Hamilton almost thirty years ago and intensive work by many people since then, we are still trying to answer those questions, of course, with quite some success along the way.
