Covering and paired domination in intuitionistic fuzzy graphs

Abstract

The concepts of covering and matching in an intuitionistic fuzzy graph using strong arcs are introduced and established many interesting properties on it. The notion of paired domination in intuitionistic fuzzy graph using strong arcs is also studied. The strong paired domination number γ spr of complete intuitionistic fuzzy graph and complete bipartite intuitionistic fuzzy graph is determined and investigated many interesting properties on it.
