Trialing of the topological types of phase diagrams for unary systems

The topological isomorphism of polyhedra with tervalent vertices and phase diagrams of unary systems allows us to reduce the problem of constructing the full set of topological types of diagrams with tailored parameters to the problem of generating labeled graphs. Each of them is the Schlegel projection of some polyhedron onto one of its faces. This work concerns the problem of listing possible topological types of phase diagrams of unary systems. A great variety of the types of these diagrams is demonstrated.
