|I intend to overview some global-in-time variational techniques for evolution equations.
In particular, we shall be interested in the possible reformulation of evolution systems,
either of dissipative or dispersive type, in terms of minimization problems. The idea
is that of moving the successful machinery of the Calculus of Variations (direct method,
gamma-convergence, relaxation..) to evolutionary situations. I will in particular
present results for gradient and doubly nonlinear flows as well as for nonlinear waves.
This is joint work with Goro Akagi.
