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.File in questo prodotto:
