GADGET/First Cut lecture series: Classifying symplectic 4-manifolds and complex surfaces by
Tim Perutz (UT Austin) in RLM 9.166
One of the activities in the new NSF Research Training Grant in geometry and topology will be a series of expository video-lectures entitled "First Cut". These will be broad-brush presentations (by UT faculty/postdocs and visitors) on topics in geometry and topology, aimed at an audience of graduate students, postdocs and faculty. We expect that they will happen 2-3 times per semester, in the GADGET time-slot; they will be filmed and made available online. In this first lecture of this series, I'll give an overview of what we know and don't know about classifying compact symplectic 4-manifolds. In limited circumstances, there is a classification which closely resembles part of the Kodaira-Enriques classification of complex surfaces. In other cases, a wide divergence between complex and symplectic categories appears. Submitted by
