Independant domination number of a graph

A set S of vertices in a graph G is an independent dominating set of G if D is an independent set and every vertex not in D is adjacent to a vertex in D. Moreover, since any total co-independent dominating set is a total dominating set, we characterize all the trees having equal total co-independent domination number and total domination number. Proof — Let I be an independent dominating set of cardinality i G. Since I is independent, no two vertices of I are adjacent in G. Most users should sign in with their email address.

On locating independent domination number of amalgamation graphs

AIP Conference Proceedings, , ] Volume 3 Issue 4, — Issue 3, — Issue 2, — Issue 1, 1— Then at least two vertices, say, u , v in D , are adjacent to each other. We also study the relationship between independent [1; 2]-sets and independent dominating sets in this graph class, that allows us to obtain an upper bound for the associated parameter, the independent [1; 2]-number, in terms of the independent domination number. The authors in [7] listed over papers related to domination in graphs in over 75 variation.

It must have at least 2 vertices as it intersects both S 1 and S 2. We also investigate the degree equitable domination in the corona of graphs. Proof — Let D be a minimum dominating set which is not an independent set of G. Then S is a vertex covering transversal dominating set of G. Were these topics helpful?
