PROPERTIES OF SIMPLICIAL VERTICES IN SOME GRAPHS
K. Radha, P. Indumathi · Our Heritage · 2020
In this paper, Simplicial vertices in the direct sum of two graphs are discussed. Some of theirproperties are studied. The conditions for a vertex to be simplicial in the complement of two graphsare obtained and the conditions for a vertex to be simplicial in the complete bipartite graph, path,star, cycle and tree graphs are discussed.
