چکیده
We obtain new results on 3-rainbow domination numbers of generalized Petersen graphs P(6k,k). In some cases, for infinite families, exact values are established; in all other the lower and upper bounds with small gaps given. also define singleton rainbow domination, where sets assigned have a cardinality of, at most, one, provide analogous this special case domination.

2-rainbow domination in generalized Petersen graphs P(n, 3)
Assume we have a set of k colors and we assign an arbitrary subset of these colors to each vertex of a graph G. If we require that each vertex to which an empty set is assigned has in its neighborhood all k colors, then this assignment is called a k-rainbow dominating function of G. The corresponding invariant γrk(G), which is the minimum sum of numbers of assigned colors over all vertices of G...

متن کاملOn Power Domination of Generalized Petersen Graphs
The power dominating problem is a variation of the classical domination problem in graphs. Electricity company use phase measurement units (PMUs) to produce the measuring data of a system, and use these data to estimate states of the system. Because of the high cost of PMUs, minimizing the number of PMUs on a system is an important problem for electricity companies. This problem can be modeled ...
متن کاملRoman domination number of Generalized Petersen Graphs P(n, 2)
A Roman domination function on a graph G = (V,E) is a function f : V (G) → {0, 1, 2} satisfying the condition that every vertex u with f(u) = 0 is adjacent to at least one vertex v with f(v) = 2. The weight of a Roman domination function f is the value f(V (G)) = ∑ u∈V (G) f(u). The minimum weight of a Roman dominating function on a graph G is called the Roman domination number of G, denoted by...
متن کاملDouble Total Domination on Generalized Petersen Graphs
A set S of vertices in a graph G is a double total dominating set, abbreviated DTDS, of G if every vertex of G is adjacent to least two vertices in S. The minimum cardinality of a DTDS of G is the double total domination number of G. In this paper, we study the DTDS of the generalized Petersen graphs. Mathematics Subject Classification: 05C35
