        "description":"The goal of this talk is to showcase how we can use stochastic processes to study the geometry of surfaces. After recalling basic facts about surfaces with constant curvature, their length spectrum, and Brownian motion on them, we use the Brownian loop measure to express the lengths of closed geodesics on a hyperbolic surface and zeta-regularized determinant of the Laplace-Beltrami operator. This gives a tool to study the length spectra of a hyperbolic surface and we obtain a new identity between the length spectrum of a compact surface and that of the same surface with an arbitrary number of additional cusps.",

But the bur oak is no lone wolf: it exchanges genes with other oak species from the Black Hills to Vermont, and from northern Minnesota to Texas. This talk will provide an overview of ongoing rangewide and reciprocal transplant studies of bur oaks undertaken as part of a collaborative NSF - NSFC Dimensions of Biodiversity project, \u201cConsequences of diversity in Asian and American tree syngameons for functional variation, adaptation and symbiont biodiversity.\u201d It will present analyses of genomic, trait, mycorrhizal, and gall wasp data to provide an integrative view of how bur oaks and their relatives shape the forest.",
