Abstract

We first introduce the concept of \((k, k’, k”)\)-domination numbers in graphs, which is a generalization of many domination parameters. Then we find lower and upper bounds for this parameter, which improve many well-known results in the literature.

Keywords: (k,k’,k”)-domination number, k-domination number, restrained domination numbers. MSC 2000: 05C69
