Ak. Frolkova et La. Serafimov, Topological structure of state regions and isothermic-isobaric manifolds for multiphase systems, THEOR F CH, 34(3), 2000, pp. 286-291
A general formula is derived for the invariant of the isothermic-isobaric m
anifold. The structure of the manifold is examined for multiphase systems w
ith various numbers of components.
