Abstract
An analysis of topology of two-dimensional isothermal potential phase diagrams of partially open immiscible condensed systems is presented. The systems share two independent components with surroundings. Chemical potentials (or derived properties such as activities or relative partial pressures) of these two independent components are used as coordinates of such diagrams. Several theorems on topology having practical consequences are proved.
