Perfect Roman and Perfect Italian Domination of Cartesian Product Graphs
For a graph G=(V,E), a function f:V→{0,1,2} is a perfect Roman dominating function (PRDF) on G if every v∈V with f(v)=0 is adjacent to exactly one vertex u with f(u)=2. The sum ∑_(v∈V)^▒f (v) is the weight w(f) of f. The perfect Roman domination number γ_R^p (G) of G is least positive integer k such...
