PIMS/Shell Lunchbox Lecture: Oceans and Multiplicative Ergodic Theorems

Topic

Details

In many physical processes, one is interested in mixing and obstructions to mixing: warm air currents mixing with cold air; pollutant dispersal etc. Analogous questions arise in pure mathematics in dynamical systems and Markov chains. In this talk, I will describe the relationship between obstructions to mixing and eigenvectors of transition operators; in particular I will focus on recent work on the non-stationary case: when the Markov chain or dynamical system is non-homogeneous, or when the physical process is driven by external factors.

I will illustrate my talk with analysis of and data from ocean mixing.

Anthony Quas, University of Victoria

 

Dr. Quas is a professor in the Department of Mathematics and Statistics at the University of Victoria, where he holds a Canada Research Chair. He obtained his Ph.D. at the University of Warwick (UK) and his recent academic distinctions include being editor of the journal Dynamical Systems and an organizer of the MSRI program on Additive Combinatorics and Ergodic Theory. He is also the managing editor of PIMS’ Pi in Sky magazine.

His research expertise covers a range of topics in ergodic theory and dynamical systems. In particular, his work has included work on symbolic dynamics and the ergodic theory of differentiable dynamical systems and their connections with stochastic processes.
