    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...

  • 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 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...

    Jordan algebras are the most natural type of algebras associated with finitely additive measures. Some consequences of this class of algebras are found. In particular, the questions of, what is the nature of the σ-algebra generated by the Jordan algebra? when the Jordan ...

    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...

    <jats:p>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 prope...

    Let G = (V, E) be a simple connected undirected graph. In this paper, we define generalized the divisor sum Tk-function of a graph which is the summation of the sum of divisor k-function of the degree of the vertices of a graph denoted by Tk(G) = P v2V(G) k(deg(v)) and ...
