Abstract
It is proved that, in the critical region above Tc, the boundary susceptibility of a lattice is approximately (T-Tc)-γ-v. It is argued that the boundary tension is approximately (Tc-T)μ as T -> Tc-, with μ = 2-(αsprime+vprime). (αsprime, γ, v, vprime are the usual bulk indices of specific heat, susceptibility and correlation length.) The appropriate index in Macleod's law is briefly discussed.Keywords
