Tel Aviv University,    Colloquium
Hello everyone,
The next colloquium talk will be held on:
Monday, 26/11/2012, 12:15, Schreiber 006, Tel Aviv University.
Speaker: Lenya Ryzhik (Stanford University)
Title: The role of a drift in elliptic and parabolic equations.
The abstract is given below. Tea and coffee at 12:00, same room.
Hope to see you there. For information about future colloquia, see
Abstract: The first order partial differential equations are closely
connected to the underlying characteristic ODEs. The second order elliptic
and parabolic equations are as closely connected to the Brownian motion
and more general diffusions with a drift. From a variety of points of
view, the drift does not really matter - all diffusions look more or less
similar. As a caveat to this reasonable line of thought, I will describe
a menagerie of problems: linear and nonlinear, steady and time-dependent,
compressible and incompressible, where the drift and diffusion
confirm the Mayakovsky thesis "Woe to one alone!" Together, they
lead to enhanced mixing and improved regularity that are impossible for
each one of them to attain. Illustrations range from combustion to
coral reproduction.
