Graph homeomorphism

Webhomeomorphism, in mathematics, a correspondence between two figures or surfaces or other geometrical objects, defined by a one-to-one mapping that is continuous in both directions. The vertical projection shown in the figure sets up such a one-to-one correspondence between the straight segment x and the curved interval y. In this article, unless stated otherwise, graphs are finite, undirected graphs with loops allowed, but multiple edges (parallel edges) disallowed. A graph homomorphism f from a graph to a graph , written f : G → H is a function from to that maps endpoints of each edge in to endpoints of an edg…
