 eous medium - Yip\, A (Purdue)

DESCRIPTION:We will present some results for the interfacial propagation i
 n inhomogeneous medium. The prototype equation is given by motion by mean 
 curvature. The key feature is the interaction between the mean curvature o
 f the interface and the underlying spatial inhomogeneity. We will describe
  the transition between the pinning and de-pinning of the interface and th
 e existence of pulsating waves. Some recent investigations on the pinning 
 threshold\, front propagations between patterns and random walks in random
  medium will also be discussed.\n
