Selection of measure and a Large Deviation Principle for the general XY model
arXiv:1106.3118
Abstract
We consider a connected and compact manifold and we denote by the Bernoulli space . The shift acting on is denoted by . We analyze the general XY model, as presented in a recent paper by A. T. Baraviera, L. M. Cioletti, A. O. Lopes, J. Mohr and R. R. Souza. Denote the Gibbs measure by , where is the eigenfunction, and, is the eigenmeasure of the Ruelle operator associated to . We are going to prove that any measure selected by , as , is a maximizing measure for . We also show, when the maximizing probability measure is unique, that it is true a Large Deviation Principle, with the deviation function , where , and, is any calibrated subaction.
