Résumé du colloque

A one-dimensional fluid is investigated in which the particles interact with a long-range potential. With an appropriate change in the potential function, the model is also suitable for a two or three dimensional fluid with more restricted interactions. A convenient formulation of the problem is possible in terms of the Ising model formalism which permits solution in infinite series form. This leads to a unified method for obtaining low-temperature expansions of the partition function for two and three dimensional nearest-neighbor systems. The model is found to give realistic thermodynamic results.
