Title:
Toward a smooth ergodic theory for infinite dimensional systems

Speaker:
Lai-Sang Young

Abstract:
Focusing on settings that are consistent with semi-flows defined by dissipative parabolic PDEs, I will discuss some first steps toward building a dynamical systems theory, in particular a theory of chaotic systems, for maps and semi-flows in Hilbert and Banach spaces. I will survey known results and present recent progress, including theorems on Lyapunov exponents, periodic solutions and horseshoes, entropy formula and SRB measures, and a notion of “almost every” initial condition that is natural to the underlying dynamics. Technical differences between finite and infinite dimensions will also be discussed
