چکیده
Let D = (V, A) be a directed graph of order p. A subset S of the vertex set V(D) is a dominating set of D if for each vertex v∈D – S there exists a vertex u∈S such that (u, v) is an arc of D. The domination number of D, γ(D), is the order of a smallest dominating set of D. In this paper we calculate the domination number of the cartesian product of two directed paths Pm and Pn for general m and n.

On independent domination numbers of grid and toroidal grid directed graphs
A subset $S$ of vertex set $V(D)$ is an {em indpendent dominating set} of $D$ if $S$ is both an independent and a dominating set of $D$. The {em indpendent domination number}, $i(D)$ is the cardinality of the smallest independent dominating set of $D$. In this paper we calculate the independent domination number of the { em cartesian product} of two {em directed paths} $P_m$ and $P_n$ for arbi...

Let G be a graph. A 2-rainbow dominating function (or 2-RDF) of G is a function f from V(G) to the set of all subsets of the set {1,2} such that for a vertex v ∈ V (G) with f(v) = ∅, thecondition $bigcup_{uin N_{G}(v)}f(u)={1,2}$ is fulfilled, wher NG(v) is the open neighborhoodof v. The weight of 2-RDF f of G is the value$omega (f):=sum _{vin V(G)}|f(v)|$. The 2-rainbowd...

4 Let γ(Pm2Pn) be the domination number of the Cartesian product of directed paths Pm and Pn for m,n ≥ 2. In [13] Liu and al. determined the value of γ(Pm2Pn) 6 for arbitrary n and m ≤ 6. In this work we give the exact value of γ(Pm2Pn) for any m,n and exhibit minimum dominating sets. 8 AMS Classification[2010]:05C69,05C38. 10
متن کاملA Note on the Domination Number of the Cartesian Products of Paths and Cycles
Using algebraic approach we implement a constant time algorithm for computing the domination numbers of the Cartesian products of paths and cycles. Closed formulas are given for domination numbers γ(Pn Ck) (for k ≤ 11, n ∈ N) and domination numbers γ(Cn Pk) and γ(Cn Ck) (for k ≤ 7, n ∈ N).
متن کاملTotal domination number of grid graphs
We use the link between the existence of tilings in Manhattan metric with {1}-bowls and minimum total dominating sets of Cartesian products of paths and cycles. From the existence of such a tiling, we deduce the asymptotical values of the total domination numbers of these graphs and we deduce the total domination numbers of some Cartesian products of cycles. Finally, we investigate the problem ...
