Description:

Title: Interfaces in inhomogeneous media: pinning, hysteresis, and facets

Abstract:

I will discuss some models for the shape of liquid droplets on rough solid surfaces. These are elliptic free boundary problems with oscillatory coefficients. The framework of homogenization theory allows to study the large scale effects of small scale surface roughness, including interesting physical phenomena such as contact line pinning, hysteresis, and formation of facets. The talk is partly based on joint work with Charles Smart.
