Description
Title: Mixing, transport, and enhanced dissipation
Abstract: I will discuss transport of passive scalars by incompressible flows and measures of optimal mixing and stirring.
I will present two examples of opposite effects of mixing: one leads to irregular transport and a dramatic, instantaneous loss of regularity for transport equation, the other is enhanced dissipation, which can lead to global existence in non-linear, dissipative systems. In particular, I will show how mixing leads to global existence for the 2D Kuramoto-Sivashisky equation, a model for flame propagation.
Location: Hamilton Hall, Room 305
Coffee and Cookies will be served in Hamilton Hall Lounge at 3:00 pm.
