In this paper, we introduce the notion of semi-open sets and feebly open sets in generalized topological spaces. Several properties of these notions are discussed. Also this paper considers (semi and feebly)-separation axioms for generalized topological s... see more

In this paper, we give some characterizations of the left and right generalized Drazin invertible bounded operators in Banach spaces by means of the single-valued extension property (SVEP). In particular, we show that a bounded operator is left (resp. rig... see more

We use the theta omega closure operator to define theta omega connectedness as a property which is weaker than connectedness and stronger than ?-connectedness. We give several sufficient conditions for the equivalence between ??-connectedness and connecte... see more

Let G be a group, let s : G ? G be an involutive automorphism and let ?1, ?2 : G ? C* be two characters of G such that ?2(xs(x)) = 1 for all x ? G. The aim of this paper is to describe the solutions f, g : G ? C of the functional equation ?1(y)f (xy) + ?2... see more

Our aim is to establish the existence of weak solution for a class of Robin problems involving fourth order operator. The nonlinearity is superlinear but does not satisfy the usual Ambrosetti-Rabinowitz condition.The proof is made with and without variati... see more

We prove that if (U, ?) is a finite dimensional generalized alternative b-algebra II over a field F of characteristic different from 2 and 3, then rad(U) = R(U) ? (bar(U))3.

Approximation of functions of different classes have been considered by various researchers under different summability means. In the present paper, presumably a new theorem has been established under (E, 1)(N¯ pn) -product summability mean of conjugate F... see more

A set S of vertices in a graph G is called a dominating set of G if every vertex in V (G)\S is adjacent to some vertex in S. A set S is said to be a power dominating set of G if every vertex in the system is monitored by the set S following a set of rules... see more

In this paper we have extended the notion of statistical limit point as introduced by Fridy[8] to I-statistical limit point of sequences of real numbers and studied some basic properties of the set of all Istatistical limit points and I-statistical cluste... see more

A zero-sum flow is an assignment of nonzero integers to the edges such that the sum of the values of all edges incident with each vertex is zero, and we call it a zero-sum k-flow if the absolute values of edges are less than k. We recall the zero-sum flow... see more

In this article, we introduce the concept of µ-statistical convergence and µ-density convergence of sequences of functions defined on a compact subset D of the probabilistic normed space (X, N, *), where µ is a finitely additive two valued measure. In par... see more

The aim of this work is to establish further existence of solution results for quantum stochastic differential equations with unbounded coefficients, which are also stochastic processes. Existence of solutions for nonlocal quantum stochastic differential ... see more

A star coloring of a graph G is a proper vertex coloring in which every path on four vertices in G is not bicolored. The star chromatic number ?s (G) of G is the least number of colors needed to star color G. In this paper, we have generalized the star ch... see more

Distance is an important graph invariant that has wide applications in computing science and other fields of sciences. A topological index is a genuine number connected with compound constitution indicating for relationship of compound structure with diff... see more

In the present paper, by using the Lp,q,n(x) functions, our methodology intertwine to yield the Theory of Geometric Functions and that of Special Functions, which are usually considered as very different fields. Thus, we aim at introducing a new class of ... see more
