In this paper, we introduce the probabilistic normed groups. Among other results, we investigate the continuityof inner automorphisms of a group and the continuity of left and right shifts in probabilistic group-norm. We also study... more
In this paper, first we define and study the probabilistic n-normed spaces and D-n-compactness, also we prove some theorems and inequalities. In the next section we define D-n-boundedness and prove some results in relation between... more
In this paper, we introduce an inner product on abelian groups and, after investigating the basic properties of the inner product, we first show that each inner product group is a torsion-free abelian normed group. We give examples of... more
Abstract. K. Menger introduced the notion of probabilistic metric spaces. The idea of Menger was to use distribution function instead of nonnegative real numbers as values of the metric. The concept of probabilistic normed spaces were... more
In this paper, first we define and study the probabilistic n-normed spaces and Dn-compactness, also we prove some theorems and inequalities. In the next section we define Dn-boundedness and prove some results in relation between... more
The purpose of this paper is to prove some common fixed point theorems for a pair of R-weakly commuting mappings defined on intuitionistic fuzzy metric spaces [Park JH. Intuitionistic fuzzy metric spaces. Chaos, Solitons & Fractals... more
ABSTRACT The aim of this paper is to give necessary conditions to get bounded linear operators in random 2-normed linear spaces and to study the relation between the boundedness and continuity of a linear operator in random 2-normed... more
This paper examined the relationship between Mathematics anxiety, Mathematics performances and overall academic performance in high school students. 424 (111 males and 113 females) of high school students from three states in South India,... more
In this paper, first, using interpolative Kannan type contractions, a new fixed point theorem has been proved. Then, by applying sequentially convergent mappings and using subadditive altering distance functions, we generalize... more
In this paper, a D2D multiple-metric routing protocol is proposed in the situation that the network infrastructures are ruined due to a possible natural disaster. To improve the stability and the shortness of the path, we use fuzzy... more
In this paper, after introducing inner products on groups, first, we define a Hilbert group using the inner products and in the last section, we present some fixed points for closed and midconvex subgroups of such Hilbert groups.
In this paper, we give a probabilistic counterpart of Mazur-Ulam theorem in probabilistic normed groups. We show, under some conditions, that every surjective isometry between two probabilistic normed groups is a homomorphism.
In this paper, a device-to-device (D2D) communication multiple-metric scenario for resource allocation and pairing is proposed. To improve the stability of the D2D connection, a fuzzy method based on the data-rate and battery levels of... more
