Abstract
An edge Italian dominating function (EIDF) of a graph G = (V,E) is a function f : E(G) → {0, 1, 2} such that every edge x with f(x) = 0 is adjacent to some edge y with f(y) = 2 or adjacent to at least two edges z1, z2 withf(z1) = f(z2) = 1. The weight of an edge Italian dominating function is the sum P x∈E(G) f(x) and the minimum weight of an edge Italian dominating function of G is called the edge Italian domination number of G and is denoted by Γ' I(G). In this paper, we determine the edge Italian domination number of some graph products.
