摘要: In this paper we review two important theoretical areas to which J. W. Cahn has made major contributions: (i) The theory of the ξ-vector developed by Hoffman and Cahn, provides an elegant setting for description equilibrium shapes sharp interfaces in presence anisotropic surface energy. (ii) Diffuse interface theories phase transitions. We describe recent work connects these complementary facets models development a generalized diffuse with show that plays central role both mathematical physical aspects wide range either energy or attachment kinetics.
