Motion of Anisotropic Interfaces

The dependence of the physical properties of an interface on its spatial orientation can have profound and dramatic effects on its motion. This anisotropy can come from a variety of sources, for example, variation of surface energy and kinetic mobility due to an internal crystal lattice, externally imposed elastic fields or from local orientational order of polymer and liquid crystal molecules. The speakers in this session will discuss a variety of experimental observations on and mathematical models of anisotropic interface motion.
