Abstract: The Ricci flow has been a powerful tool in the study of three-dimensional manifolds. I will discuss the behavior of this flow on an important class of four-dimensional manifolds: the Kahler surfaces. In addition, I will discuss a flow which generalizes the Kahler-Ricci flow called the Chern-Ricci flow. This is a geometric flow on complex manifolds, recently introduced by M. Gill. I will describe some recent results and conjectures in the case of complex surfaces.

Here are some directions to Northeastern University. Lake Hall and Nightingale Hall can be best accessed from the entrance on the corner of Greenleaf Street and Leon Street. The two halls are connected, with no well-defined boundary in between. In particular, 509 Lake Hall is on the same corridor as 544 Nightingale Hall.

There is free parking available for people coming to the Colloquium at Northeastern's visitor parking (Rennaisance Garage). The entrance is from Columbus Avenue. If coming by car, you should park there and take the parking talon. After the lecture, you may pick up the payment coupon from Jonathan Weitsman.
