## Abstract We investigate vertexβtransitive graphs that admit planar embeddings having infinite faces, i.e., faces whose boundary is a double ray. In the case of graphs with connectivity exactly 2, we present examples wherein no face is finite. In particular, the planar embeddings of the Cartesian
## Abstract Let __N__(Ξ³, Ξ³β²) denote the size of the smallest complete graph that cannot be edgeβpartitioned into two parts embeddable in closed orientable sufaces of genera Ξ³, Ξ³β², respectively. Wellβknown embedding theorems are used to obtain several infinite families of values of __N__(Ξ³, Ξ³β²). Som
In this article, we characterize all signless Laplacian integral graphs (here called Q -integral graphs) in the following classes: complete split graphs, multiple complete split-like graphs, extended complete split-like graphs, multiple extended split-like graphs. All these graphs were defined by Ha
