Summary: [For the entire collection see Zbl 0638.00009.]
Let G be a finite rooted directed multigraph. With each such G is associated an algorithmically constructed graph CF(G) of the same type. It is demonstrated that the spaces of unending paths in two finite rooted directed multigraphs G and G’ are homeomorphic if and only if the graphs CF(G) and CF(G’) are isomorphic. It is shown that a topological space is homeomorphic with the space of unending paths in such a graph G if and only if it is compact, zero-dimensional, metrizable and of finite type.
