A family of parameter-dependent functionals defi ned over entire trajectories is introduced and proved to admit global mi nimizers. These global minimizers correspond to solutions of elliptic-in-t ime regularizations of the limiting causal problem. By passing to the limi t in the parameter\, such global minimizers converge\, up to subsequences\ , to a solution of the gradient flow. After discussing such variational fo rmulation in the context of classical gradient flows\, we will focus on th e semilinear gradient flows with state-dependent dissipation.\nThis is par tly based on a joint work with Goro Akagi and Ulisse Stefanelli.\n LOCATION:https://researchseminars.org/talk/NSCM/157/ END:VEVENT END:VCALENDAR
