ABSTRACT

For many application areas, it is becoming important to understand transport mechanisms underlying time-dependentdynamical systems. In particular, it is interesting to identify coherent sets, which are minimally dispersive as moving with the flow and typically present important physical structures such as long-lived vortices in oceans or atmosphere. This presentation will concentrate on a transfer operator approach for a finite-time coherent set identification. Few illustrative examples of its application in a geophysical model and atmospheric flow will be presented.
