✦ Synopsis

AbstraetXrystal surfaces below their roughening temperature possess step patterns. The timeevolution of these patterns determined the growth rate of the crystal face. An equation of motion for arbitrary step patterns is presented. As an example this equation is applied to the problem of nucleation between straight steps. An expression for the minimal step distance for this nucleation process is derived.

## Abstract We apply the principle of linearized stability to prove that a stationary state is exponentially stable under a mirror–symmetric three phase boundary motion by surface diffusion. A main difficulty in the application of the linearized stability principle arises from the inhomogeneous non
