Title : On Liouville Brownian rough paths
Abstract : A Riemannian metric gives rise to the Laplace-Beltrami operator which generates, as Markov process, a natural symmetric diffusion process known as Brownian motion. About 10 years ago, Garban-Rhodes-Vargas and (simultaneously) Berestycki introduced "Liouville Brownian motion", based on a highly singular metric, obtained by multiplying the planar Euclidean metric by the exponential of the Gaussian free field. I will report on a project with Sebastian Andres (Manchester) and Yizheng Yuan (Cambridge) on the construction of Liouville Brownian rough paths.
