Abstract:

A k-bisection of a graph G is a partition of its vertex set into two parts V-1 and V-2 of the same cardinality such that every connected component of the subgraph of G induced by V-1(i = 1, 2) has at most k vertices. Ban and Linial conjectured that every bridgeless cubic simple graph admits a 2-bisection except for the Petersen graph. Recently, Abreu et al. showed that Ban-Linial's conjecture is true for bridgeless claw-free cubic simple graphs. In this short note, we prove a stronger result. We show that for any (not necessarily bridgeless) claw-free cubic multigraph G and for any edge e is an element of E(G), there exists a 2-bisection of G such that the two endvertices of e belong to different parts.
