Abstract

Suppose G=(V,E,F) is a finite plane graph with vertex set V(G), edge set E(G), and face set F(G). A bijection λ:V(G)E(G)F(G){1,2,3,,|V(G)|+|E(G)|+|F(G)|} is called a labeling of type (1,1,1). The weight of a face under a labeling is the sum of the labels (if present) carried by that face and the edges and vertices surrounding it. A labeling of a plane graph G is called d-antimagic if for every number s3, the set of s-sided face weights isWs={as+id:0ifs} for some integers as and d (a>0, d0), where fs is the number of s-sided faces. We allow different sets Ws for different s.
In this paper, we deal with d-antimagic labelings of type (1,1,1) for a special class of plane graphs Cab and we show that a Cab graph has d-antimagic labeling for d{a2,a1,a+1,a+2}.
