One-sided Mullins-Sekerka flow does not preserve convexity

Electron. J. Differ. Equ. 1993(8), (1993)

Summary

Summary: The Mullins-Sekerka model is a nonlocal evolution model for hypersurfaces, which arises as a singular limit for the Cahn-Hilliard equation. Assuming the existence of sufficiently smooth solutions we will show that the one-sided Mullins-Sekerka flow does not preserve convexity.
