✦ Synopsis

%rSiI. J.. Characterization of signed graphs which are cellularly emheddahle in no more than one surface. Discrete Mathematics 94 (1991) 39-44. We consider embeddings of signed graphs in which the balanced cycles of .he graph mducs orientation-preserving cycles on the surface. and characterize those signed graphs which are (in this sense) cellularly emheddahle in a unique closed surface.
