Title: Phase transitions in binary lattice gases
Abstract: We prove the existence of phase transitions in several kinds of two component lattice gases: Some of these are isomorphic to spin systems and/or to fluids composed of asymmetrical molecules which can have different orientations. Among the models studied is one with infinite repurlsion between particles of different species (hard vores), extending over arbitrarily many neighboring latice sites. Some of these systems have been investigated previously in the mean field approximation and numerically.
