We give a proof of Guenin's theorem characterizing weakly bipartite graphs by not having an odd-K 5 minor. The proof curtails the technical and case-checking parts of Guenin's original proof.

## Abstract A graph __G__ = (__V__, __E__) is called weakly fourโconnected if __G__ is 4โedgeโconnected and __G__ โ __x__ is 2โedgeโconnected for all __x__ โ __V__. We give sufficient conditions for the existence of โsplittableโ vertices of degree four in weakly fourโconnected graphs. By using thes
For two integers a and b, we say that a bipartite graph G admits an (a, b)bipartition if G has a bipartition (X, Y ) such that |X| = a and |Y | = b. We say that two bipartite graphs G and H are compatible if, for some integers a and b, both G and H admit (a, b)-bipartitions. In this paper, we prove
Let 8 be a bipartite graph with edge set โฌand vertex bipartition M, N. The bichromaticity p ( 6) is defined as the maximum number p such that a complete bipartite graph on p vertices is obtainable from 5 by a sequence of identifications of vertices of M or vertices of N. Let p = max{lMI, IN\}. Hara
