Introductory description

This will be an introduction to variational analysis as opiated with evolution equations. The goal of this course is to introduce some fundamental concepts, methods and theory associated with the mathematical theory of time dependent PDEs and related models. The essence will be the abstract theory of variational formulations of parabolic and second order evolution equations and the theory of gradient flows. Motivation comes from physical, life and social sciences.
