This Wednesday we will have **two** applied maths seminars. In the morning at 11am, Kasun Fernando (Brunel University) will speak to us in Carslaw 452. This will be followed by lunch on campus. Title: A Dolgopyat-type estimate for a class of 2D partially hyperbolic systems Abstract: In this talk, I will discuss a Dolgopyat-type estimate for a class of partially hyperbolic systems on the 2-Torus, and its consequences: the CLT, its higher order corrections, and exponential decay of correlations for a class of three-dimensional skew products. This is a joint work with Roberto Castorrini.
