Outer-Connected Semitotal Double Roman Dominating Function in Graphs.

Abstract

In this paper, we establish the study of outer-connected semitotal double Roman domination. A function f is said to be an outer-connected semitotal double Roman dominating function of a graph G if it is a double dominating function and satisfies the condition for outer-connected semitotal. Our results consist of some bounds of the parameter and characterization of graphs G with specified values of the parameter.
