The concept of split domination number was introduced by Kulli and Janakiram. Fink Jacobson the notion k-domination in graphs. In this paper, we acquaint with k-split k-non for some zero-divisor graphs ϑ-Obrazom
For any k ∈ N, the k-subdivision of a graph G is a simple graph G 1 k , which is constructed by replacing each edge of G with a path of length k. In [Moharram N. Iradmusa, On colorings of graph fractional powers, Discrete Math., (310) 2010, No. 10-11, 1551-1556] the mth power of the n-subdivision of G has been introduced as a fractional power of G, denoted by G m n . In this regard, we investig...
The domination number of graph is the smallest cardinality set G. A subset a vertex S G called if every element dominates G, meaning that not an connected and one distance from S. has become interesting research studies on several graphs k -connected such as circulant graphs, grids, wheels. This study aims to determine other k-connected Harary graph. method used pattern detection axiomatic dedu...
Let G=(V(G),E(G)) be a graph.A set of vertices S in a graph G is called to be a Smarandachely dominating k-set, if each vertex of G is dominated by at least k vertices of S. Particularly, if k = 1, such a set is called a dominating set of G. The Smarandachely domination k -number γk(G) of G is the minimum cardinality of a Smarandachely dominating k -set of G. S is called weak domination set if ...
The broadcast domination problem of a graph G = (V,E) is to find a subset B ⊆ V such that the vertices in V \B can be dominated by some vertex in B. The difference between broadcast domination and classical domination is that each vertex v in B is assigned a power value f(v) where f(v) ≥ 1 and the vertices in distance at most f(v) to v can hear (be dominated by) v. The goal is to find the minim...
The last years there is an increasing interest for query processing techniques that take into consideration the dominance relationship between items to select the most promising ones, based on user preferences. Skyline and top-k dominating queries are examples of such techniques. A skyline query computes the items that are not dominated, whereas a top-k dominating query returns the k items with...
