Antiself dual Lagrangians and variational formulations for non selfadjoint boundary value problems and dissipative evolutions
We develop a theory of antiself dual Lagrangians that allows for variational
formulations and resolutions of many boundary value and initial value problems
which normally cannot be obtained as EulerLagrange equations of action functionals.
Examples include nonpotential operator equationslike nonlinear transport and
others involving first order nonselfadjoint differential operatorsas well as
dissipative evolution equationslike the heat equation, porous media, other
gradient flows but also the NavierStokes equations.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge,
Math Annex (Room 1115).
