In this paper, we introduce a new class of sets called τ *-generalized closed sets and τ *-generalized open sets in topological spaces and study some of their properties .
We introduce a new set called smg-closed which are defined on a family of sets satisfying some minimal conditions. It is investigated that this set is a stronger form of mg-closed sets due to T. Noiri. This set enable us to unify certain kind of modifications of strongly generalized closed sets due to Sundaram and Pushpalatha .
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 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.wg-closed… (More)
The aim of this paper is to introduce and study the concepts of prefilters in intuitionistic fuzzy topological spaces.
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)
A bijection f: (X,) → (Y, σ) is called regular weakly homeomorphism if f and f-1 are rw-continuous. Also we introduce new class of maps namely rw-homeomorphism. This class of maps is closed under composition of maps.
In this paper, some fundamental technical concepts of the main multiple access schemes for wireless mobile systems are reviewed, and a path for development of appropriate multiple access technologies for next-generation mobile networks, or so-called beyond 3G (B3G), is established. We first review the multiple access technologies in second-and… (More)
In this paper, we investigate the intuitionistic fuzzy net on the intuitionistic fuzzy topological space and we show that there is a relation between the convergence of intuitionistic fuzzy nets and prefilters.
In this paper, we have introduced a new classes of closed sets, as weaker forms of closed sets namely sc*g-closed sets and continuous functions in topological spaces.
