    A note on the dominating circuit conjecture and subgraphs of essentially 4-edge-connected cubic graphs

  • Original language description

    The well-known dominating circuit conjecture has several interesting reformulations, for example conjectures of Fleischner, Matthews and Sumner, and Thomassen. We present another equivalent version of the dominating circuit conjecture considering subgraphs of essentially 4-edge-connected cubic graphs. Let S={u1,u2,u3,u4} be a set of four distinct vertices of a graph G and V2(G) be a set of all vertices of degree 2 of a graph G. We say that G is S-strongly dominating if the graph arising from G after adding two new edges e1=xy and e2=wz such that {x,y,w,z}=S has a dominating closed trail containing e1 and e2. We show that the dominating circuit conjecture is equivalent to the statement that any subgraph H of an essentially 4-edge-connected cubic graph with V2(H)=4 and minimum degree ?(H)=2 is strongly V2(H)-dominating
