More Results on Co – Isolated Locating Domination Number of Graphs


S. Muthammai, N. Meenal
Abstract

Let G (V, E) be a simple, finite and undirected connected graph. A nonempty set S V of a graph G is a dominating set, if every vertex in V – S is adjacent to atleast one vertex in S. A dominating set S V is called a locating dominating set, if for any two vertices v, w V – S, N(v) S N(w) S. A locating dominating set S V is called a co – isolated locating dominating set (cild – set), if there exists atleast one isolated vertex in . The domination number (G) of a graph G is the minimum cardinality of a dominating set. The locating domination number ld(G) and co – isolated locating domination number cild(G) are defined in the same way. A partition of V(G), all of whose classes are cild – sets in G is called a co – isolated locating domatic partition of G. The maximum number of classes of a co – isolated locating domatic partition of G is called the co – isolated locating domatic number of G and denoted by dcild(G). In this paper, connected graphs satisfying the relation cild(G) ld(G) (G) are constructed. Also the bounds for dcild(G) are obtained.
