Some Upper Bounds for Signed Star Domination Number of Graphs
Let G be a graph with the vertex set V (G) and edge set E(G). A function f : E(G) → {−1,+1} is said to be a signed star dominating function ofG if ∑ e∈EG(v) f(e) ≥ 1, for every v ∈ V (G), where EG(v) = {uv ∈ E(G) |u ∈ V (G)}. The minimum of the values of ∑ e∈E(G) f(e), taken over all signed star dominating functions f on G is called the signed star domination number of G and is denoted by γss(G...
متن کاملUpper bounds on the paired-domination number
A set S of vertices in a graph G is a paired-dominating set of G if every vertex of G is adjacent to some vertex in S and the subgraph induced by S contains a perfect matching. The minimum cardinality of a paired-dominating set of G is the paireddomination number of G, denoted by γpr (G). In this work, we present several upper bounds on the paired-domination number in terms of the maximum degre...
متن کاملUpper Bounds on the Total Domination Number
A total dominating set of a graph G with no isolated vertex is a set S of vertices of G such that every vertex is adjacent to a vertex in S. The total domination number of G is the minimum cardinality of a total dominating set in G. In this paper, we present several upper bounds on the total domination number in terms of the minimum degree, diameter, girth and order.
متن کاملImproved upper bounds for the k-tuple domination number
We improve the generalized upper bound for the k-tuple domination number given in [A. Gagarin and V.E. Zverovich, A generalized upper bound for the k-tuple domination number, Discrete Math. 308 no. 5–6 (2008), 880–885]. Precisely, we show that for any graph G, when k = 3, or k = 4 and d ≤ 3.2, γ×k(G) ≤ ln(δ−k + 2) + ln ( (k − 2)d + ∑k−2 m=2 (k−m) 4min{m, k−2−m} d̂m + d̂k−1 ) + 1 δ − k + 2 n, and,...
متن کاملNote on Upper Bounds for TSP Domination Number
The Asymmetric Traveling Salesman Problem (ATSP) is stated as follows. Given a weighted complete digraph (K∗ n, w), find a Hamilton cycle (called a tour) in K∗ n of minimum cost. Here the weight function w is a mapping from A(K∗ n), the set of arcs in K∗ n, to the set of reals. The weight of an arc xy of K∗ n is w(x, y). The weight w(D) of a subdigraph D of K∗ n is the sum of the weights of arc...
