The blict graph and blitact graph of a graph

Open publisher page 1 citations

Abstract

In this paper, we introduce the concepts of the blict graph and blitact graph of a graph. We obtain some properties of these graphs. We present characterizations of graphs whose blict graphs and blitact graphs are planar, outerplanar, maximal outerplanar and minimally nonouterplanar. We also characterize those graphs whose blict graphs and blitact graphs are isomorphic.
