Abstract
The recently derived Fortuin, Kasteleyn and Ginibre (FKG) inequalities for lattice gasses are investigated for higher order Ising spin systems and multi-component lattice gasses. Conditions are given for the validity of the FKG inequalities for higher order spin systems with Hamiltonians of the form used recently as models for various physical systems, e.g. He3-He4 mixtures. We also investigate various inequalities for binary lattice gases and show how these can be carried over to continuum systems.
