Organizational Meeting
Abstract: We'll be chatting about the papers we're going to discuss this semester. Possibilities include: 1) Witten's Gauge theoretic interpretation of Kovanov homology of knots (these are they same equations he proposed for Geometric Langlands) 2) Extremals of the determinant of the Laplacian and uniformization. In dimension 2 the fundamental paper would be the one by Osgood, Phillips and Sarnak: http://www-ee.stanford.edu/~osgood/papers/extremals1988.pdf 3)Manning's work on the behavior of volume growth entropy along Ricci Flow in the setting of surfaces.

Volume growth entropy decreases along Ricci Flow
Abstract: We will sketch Manning's proof that the volume growth entropy for a Riemannian metric on a compact genus $g$ surface decreases along Ricci flow, modulo some black boxes. We will discuss some open problems and make some unfounded speculation.

Compactness of isospectral manifolds
Abstract: We will commence our study of the Osgood-Phillips-Sarnak papers on the compactness of isospectral surfaces. I will discuss compactness of isospectral sets of manifolds with a curvature bound. In a follow-up talk I will discuss the case of surfaces.
