Secure Complementary Tree Domination Number of a Graph

Abstract

Let G be a nontrivial connected graph, a secure dominating set D of V is said to be a secure complementary tree dominating set if the induced subgraph < V – D > is a tree. A secure complementary tree dominating sets of the graph G, having minimum cardinality is called the secure complementary tree domination number denoted by γsctd of G. We have determined the exact values of secure complementary tree domination number for some standard graphs and obtained bounds for this new parameter. NORDHAUS – GADDUM type results are attained .The relationship of this parameter with other graph theoretical parameters are also discussed.
