DESCRIPTION:Title: Quantitative Homogenization of the Invariant Measure for
  Nondivergence Form Elliptic Equations\n\nAbstract:\n\nIn this talk\, I wi
 ll first give an overview of stochastic homogenization for nondivergence f
 orm elliptic equations\, and its probabilistic counterpart\, the study of 
 quenched invariance principles for nonreversible diffusion processes. I wi
 ll then present new quantitative homogenization results for the parabolic 
 Green Function (fundamental solution) and for the unique ergodic invariant
  measure. This invariant measure is a solution of the adjoint equation in 
 doubly divergence form\, satisfying certain integrability conditions. I wi
 ll discuss the implications of these homogenization results\, such as heat
  kernel bounds on the parabolic Green function\, regularity results for th
 e adjoint equation\, and quantitative ergodicity for the environmental pro
 cess. This talk is based on joint work with Scott Armstrong and Benjamin F
 ehrman.\n\nZoom link: https://umontreal.zoom.us/j/83118539851?pwd=bk5IOXBL
