Presented by: 
Trishen Gunaratnam University of Warwick
Date: 
Wednesday 28th November 2018 - 16:00 to 16:30
Venue: 
INI Seminar Room 2
Abstract: 
We show that a class of Gaussian measures, supported on
Sobolev spaces

of high regularity, are quasi-invariant under the dynamics
of the

cubic defocusing wave equation in 3 dimensions. This is
joint work

with Tadahiro Oh, Nikolay Tzvetkov and Hendrik
Weber.
