Transport and mixing properties of dynamical systems are of interest to geophysical (among other) scientists, and they pose interesting challenges for mathematicians. For example, large scale structures such as oceanic eddies and atmospheric vortices are connected with important features of the global climate, and their detection and tracking in complex models of the real world has been an active topic of mathematical research over the last decade.

In this talk, we will introduce a powerful analytic approach, relying on so-called transfer operators, for the study of transport and mixing in both autonomous and non-autonomous (time-dependent) systems. We will also discuss recent advances and challenges at the computational and theoretical levels, ranging from mixing optimisation problems to the detection of coherent structures.
