Let G = ( Y E ) be an undirected graph. A subset F of E is a matching cutset of G if no two edges of Fare incident with the same point, and G-F has more components than G. ChGatal [2] proved that it is NP-complete to recognize graphs with a matching cutset even if the input is restricted to graphs w
We investigate some properties of graphs whose cycle space has a basis constituted of triangles ('null-homotopic' graphs). We obtain characterizations in the case of planar graphs, and more generally, of graphs not contractible onto Ks. These characterizations involve separating subsets and decompos
