Quasi-static evolution end contact angle hysteresis in capillarity

ABSTRACT: In the first part of this talk, I will recall the notion of
quasi-static evolution (or rate-independent dissipative process)
focusing on the simple model of a point mass subject to dry (or
contact), and then describe the standard approach to existence results
by time-discretization. In the second part, I will show how the
hysteresis of contact angle of a capillary drop sitting on a solid
surface can be modelled by introducing a simple frictional force on the
contact line. If time permits, I will describe the existence result for
the corresponding quasi-static evolution. This is a joint work with
Antonio De Simone (SISSA).
