Complex Geometry: A Conference Honoring Simon Donaldson

Title: The Kahler-Ricci flow on Hirzebruch surfaces
Speaker: Ben Weinkove
Speaker Info: University of California, San Diego
Brief Description:
Special Note:

I will discuss the metric behavior of the Kahler-Ricci flow on Hirzebruch surfaces assuming that the initial metric is invariant under a maximal compact subgroup of the automorphism group. I will describe how, in the sense of Gromov-Hausdorff, the flow either shrinks to a point, collapses to P1 or contracts an exceptional divisor. This confirms a conjecture of Feldman-Ilmanen-Knopf. This is a joint work with Jian Song.
