On Triangular Sum Labeling of Graphs
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 7
Abstract
Let G = (V,E) be a (p, q)-graph. A graph G is said to admit a triangular sum labeling, if its vertices can be labeled by non-negative integers so that the values on the edges, obtained as the sum of the labels of their end vertices, are the first q triangular numbers. In this paper, we obtain a necessary condition for an eulerian graph to admit a triangular sum labeling and show that some classes of graphs admit a triangular sum labeling. Also we show that some classes of graphs can be embedded as an induced subgraph of a triangular sum graph.
