Enough condition in terms of lower cut sets are given for the strong insertion of a contra-continuous function between two comparable contra-b-continuous real-valued functions on such topological spaces that kernel of sets is open.

In this paper we consider the problem of an infinitely long annular cylinder whose inner and outer surfaces are subjected to known surrounding temperatures and are traction free. The problem is in the context of the theory of thermoelasticity without ener... see more

This work, introduces an improve Poisson distribution function. This improved Poisson is equipped with some financial terms, which generate a model for determining the prices of a European call and put option for two period models. Some of its important s... see more

In the present work, we first introduce five new quadruple hypergeometric series and then we give integral representations of Euler type and Laplace type for these new hypergeometric series, which we denote by

We present an alternative deduction of the Gould’s relation for Stirling numbers of the second kind. Our approach is based in the Nörlund polynomials and in the duality property between the Stirling numbers.

C. MacDuffee apparently was the first to point out, in private communications, that a full-rank factorization of a matrix A leads to an explicit formula for its Moore-Penrose’s inverse A+. Here we apply this idea of MacDuffee and the Singular Value Decomp... see more

In this paper, we discuss the existence, uniqueness and stability of nonlinear neutral pantograph equation with ?-Hilfer fractional derivative. The arguments are based upon Schauder fixed point theorem and Banach contraction principle. Moreover&... see more
