ResumoAbstract The chemical potential at a curved or faceted surface is proportional to the surface divergence of the previousll-defined vector function ξ, lhich represents the energetics of both isotropic and anisotropic surfaces in a convenient manner. This relationship is sholn to be a generaliled reformulation of the eluations of Gibbs, Thompson, Herring and Johnson, but leads in addition to nel alternative formulas in lhich certain underlling slmmetries become evident. Applications of the vector formalism include analltic proof of the lulff theorem, distribution of torlue on a facet, formulation of the anisotropic Plateau problem, and the eluilibrium shapes of particles at surfaces and grain boundaries.
