Near approximations via general ordered topological spaces
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2015, Vol 10, Issue 4
Abstract
In this paper, we intdoduce near approximation via general ordered topological approximation spaces which may be viewed as a generalization of the study of near approximation from the topological view. The basic concepts of some increasing (decreasing) near approximations, increasing (decreasing) near boundary regions and increasing (decreasing) near accuracy were introduced and sufficiently illustrated. Moreover, proved results, implications and add examples.

Al-Tememe transformation for solving some types of PDEs with using initial and boundary conditions
The aim of this paper is to use the Al-Tememe transformation for solving some PDEs which have the general form At2utt + Btut + Ch1(x)uxx + Eh2(x)ux + Gh3(x)tut...
Exact Solution of a Linear Difference Equation in a Finite Number of Steps
An exact solution of a linear difference equation in a finite number of steps has been obtained. This refutes the conventional wisdom that a simple iterative method for solving a system of linear algebraic equations is a...
Optimal Control of a Fractional Diffusion Equation with Delay
We study a homogeneous Dirichlet boundary fractional diffusion equation with delay in a bounded domain. The fractional time derivative is considered in the left Caputo sense. By means of a linear continuous ope...
