Spectral Gap of the Laplacian for Random Hyperbolic Surfaces - Part 2

Explore an advanced mathematics seminar on the spectral gap of the Laplacian for random hyperbolic surfaces. Delve into the second part of Nalini Anantharaman's presentation, where she discusses her joint work with Laura Monk on the asymptotic behavior of the spectral gap in the limit of large genus. Examine the use of the Weil-Petersson probability measure on the moduli space of hyperbolic surfaces and the impact of M. Mirzakhani's work on this probabilistic model. Learn about the trace method employed in the proof, which utilizes asymptotic expansions in powers of g^(-1) for volume functions describing the distribution of the length spectrum. Discover how the coefficients exhibit the "Friedman-Ramanujan property" and its connection to J. Friedman's proof of the Alon conjecture for random regular graphs. Gain insights into this cutting-edge research presented at the Institute for Advanced Study's Special Groups and Dynamics Seminar.
