Abstract: | A definition of clusters of particles and holes with antiferromagnetic order is given for a lattice gas with coupling constant K < 0. In two dimensions it is shown that the Ising antiferromagnetic critical line is also a percolation line if Pb = 1 - exp(-|K|/2). Along this line these clusters called “droplets” diverge with Ising exponents. |
