Abstract:We present some new results on the region in thebeta-h plane where the + spins percolate for the nearest neighbor Ising model. In particular, it is shown that in high enough dimensionsd there is percolation of the minority spins at inverse temperaturesbeta<beta + with somebeta +>betac, for whichbeta +/gbcge1/2log(cd),c a constant.On leave from Rutgers University.
Keywords:Correlated percolation  Ising model  Peierls argument  minority spins
