One of the central problems of liquid state theory is the
determination of the phase diagram of fluids from the potential acting between its constituent particles. In accomplishing this program, a realistic description of the critical region is perhaps the most severe difficulty to be overcome. Over the past two decades, significant progress has been made in this direction. The proposed workshop will cover the theoretical and simulation approaches which include a reliable treatment of the critical behavior of fluids, thus allowing a unified description over a wide range of thermodynamic states.
