Anti-self dual Lagrangians and variational formulations for non self-adjoint boundary value problems and dissipative evolutions
We develop a theory of anti-self dual Lagrangians that allows for variational
formulations and resolutions of many boundary value and initial value problems
which normally cannot be obtained as Euler-Lagrange equations of action functionals.
Examples include non-potential operator equations--like nonlinear transport and
others involving first order non-selfadjoint differential operators--as well as
dissipative evolution equations--like the heat equation, porous media, other
gradient flows but also the Navier-Stokes equations.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge,
Math Annex (Room 1115).
