The Mullins-Sekerka model is a nonlocal evolution model for hypersurfa
ces, which arises as a singular limit for the Cahn-Hilliard equation.
We show that classical solutions exist globally and tend to spheres ex
ponentially fast, provided that they are close to a sphere initially.
Our analysis is based on center manifold theory and on maximal regular
ity. (C) 1998 Academic Press.
