    In this article, we will introduce the concept of rough vector spaces using upper approximation, and some algebraic results will be proven. Additionally, this concept will be combined with the concept of topological space.

    We consider a mathematical model describing the quasi-static process of contact between a thermo-electroviscoelastic body and a rigid foundation. The contact is described by Signorini’s conditions. The variational formulation leads to a coupled system for the displaceme...

    We study the concept of fλ-statistical convergence in a probabilistic normed space, where f is an unbounded modulus function . Also we are trying to investigate some relation between the ordinary convergence and module statistical convergence for every unbounded modulus...

    The aim of this paper is to present an overview of the active area via the spectral linearization method for solving integrable systems. New examples of integrable systems, which have been discovered, are based on the so called Lax representation of the equations of mot...

  • In this article, we have presented a variable step finite difference method for solving second order boundary value problems in ordinary differential equations with an internal boundary condition. We have discussed the convergence and established at least cubic order of ac...

    The group G ̅=2^5:SL(5,2) is a maximal subgroup of the special linear group SL(6,2) of index 2016. This Group has two inertia factor groups namely, SL(5,2) and 2^4:SL(4,2) of indices 1 and 31 respectively in SL(5, 2). The aim of this paper is to construct the Fischer-Cl...

    The topological structure is a more general mathematical model that helps in solving many problems in digital topology and its applications. In this paper, we introduce and study some general forms of separation properties based on operations. The notions of generalized...

    The aim of this article is to introduce a new form for the Laplace transform. This new definition will be considered as one of the generalizations of the usual (classical) Laplace transform. We employ the new ”Katugampola derivative”, which obeys classical properties an...

    In this paper we introduced a new notion which is called soft fuzzy metric and examined some basic properties of soft fuzzy metric spaces. Besides, some topological structures of this new space such as; soft open and soft closed sets, soft interior and soft closure of a...
