Abstract

An isolated sighed total dominating function (ISTDF) of a digraph is a function f:V(D)→{−1,+1} such that for every vertex and for at least one vertex of ,. An isolated signed total domination number of D, denoted by , in the minimum weight of an isolated signed total dominating function of D. In this paper, we study some properties of ISTDF
