A graph with signed edges is orientation embedded in a surface when it is topologically embedded so that one trip around a closed path preserves or reverses orientation according as the path's sign product is positive or negative. We find the smallest surface within which it is possible to orientation-embed the complete bipartite signed graph ±K r,s , which is obtained from the complete bipartite graph K r,s through replacing each edge by two parallel edges, one positive and the other negative. We discuss some consequences and related problems. |
