In this paper we introduce rw-closed map from a topological space X to a topological space Y as the image of every closed set is rw-closed and also we prove that the composition of two rw-closed maps need not be rw-closed map. We also obtain some properties of rw-closed maps. Generalized closed mappings were introduce and studied by Malghan[5].wg-closed(More)
In this paper, we define the notions of inverse strong non-split r-dominating set and inverse strong non-split r-domination number γ′ sns r(G) of a graph G. We characterize graphs for which γ sns r(G) + γ′ sns r(G) = n, where γ sns r(G) is the strong non-split r-domination number of G. We get many bounds on γ′ sns r(G). Nordhaus-Gaddum type results are also(More)
In this paper, we introduce the new notions í µí¼ *-g– closed sets and í µí¼ *-g– open sets í µí¼ *-g– continuous maps in Topological spaces. Also we introduce a new space called T τ *-gλ-space. We study some of its properties in Topological spaces. Keywords í µí¼ *-g– closed sets , í µí¼ *-g– open sets , í µí¼ *-g– continuous maps, T τ(More)
Malicious and selfish behaviors represent a serious threat against routing in Delay/Disruption Tolerant Networks (DTNs).We propose an iTrust, a probabilistic misbehavior detection scheme, for secure DTN routing towards efficient trust establishment. The basic idea of iTrust is introducing a periodically available Trusted Authority (TA) to judge the node's(More)
