ABSTRACT

We study mixing of passive scalars by incompressible flows and whether it is possible to construct mixing flows that achieve optimal rates of decay of the mixing scale, defined both in terms of rearrangements of sets as well as a negative Sobolev norm, under physical constraints on the flow, such as finite energy or entrosphy.
