AbstractA general type of edge colorings is described which includes many known colorings. Necessary and sufficient conditions for bicolorability are established by using simple alternating chain methods. Sufficient conditions for k-colorability are then stated. The first type of condition consists of excluding obstructions (i.e., non-bicolorable partial graphs) from the graph; the second type of condition requires some topological properties for the obstructions
