%0 Journal Article %T The Stochastic Ising Model with the Mixed Boundary Conditions %A Wang Jun %J Boundary Value Problems %D 2009 %I Springer %X We estimate the spectral gap of the two-dimensional stochastic Ising model for four classes of mixed boundary conditions. On a finite square, in the absence of an external field, two-sided estimates on the spectral gap for the first class of (weak positive) boundary conditions are given. Further, at inverse temperatures , we will show lower bounds of the spectral gap of the Ising model for the other three classes mixed boundary conditions. %U http://www.boundaryvalueproblems.com/content/2009/571950
