Fixed Point Theorems in Topological Spaces
(
Qatar University
, 2000 , Article)
A couple of theorems for a pair of self-maps on a topological space have been obtained using which certain fixed point theorems in the literature for pairs of maps satisfying contractive type conditions have been deduced.

An Extension of the Szasz-Mirakyan Operator on the Whole Real Axis
(
Qatar University
, 2000 , Article)
The aim of this paper is to present a new extension of the Szasz-Mirakyan operator n the whole real axis, and to give its convergent approximation theorem.
Cleavability of Decomposition Spaces
(
Qatar University
, 2006 , Article)
Assume that X and Y have the same homotopy type, if X (respectively Y) is cleavable over p, have proved that the decomposition space of Y/g (respectively X/f) is cleavable over p. A result ncerning Arhangel'skii - Teroni's ...
Indecomposable Representations Of Order Of E6
(
Qatar University
, 1985 , Article)
The extended Dynkin diagram
is a valued graph. We are going to construct a Baechstrom order A associateed to Eg. We prove, by constructions, that the order A of infinite lattice-type but can be listed (tame-type), i.e., ...
Theory and Computations for Systems Modeled By First Order Differential Equations
(
Qatar University
, 2000 , Article)
A numerical scheme using Sine functions is developed to approximate the solution of a 2 x 2 system of first order differential equations. The error in the approximate solution is shown to converge exponentially.
Decomposition Of The Set Of Conditionally Exponential Convex Functions
(
Qatar University
, 1993 , Article)
The theory of C* -algebra is used to develop a connection between the local extreme points and the topology of the spectrum space G.
A Mathematical Model Of The Dynamics Of Schistosomiasis
(
Qatar University
, 1996 , Article)
In this work the authors develop a mathematical model for the dynamics of a major helminth parasite of man, schistosomiasis. The model is a system of coupled non-linear equations. Numerical experimentations with the model ...
S.G. Connected Spaces
(
Qatar University
, 2000 , Article)
The purpose of this paper is to introduce and study a strongr type of connectedness called s.g connectedness in topologi-cal spaces.
Investigation Of Single-Update Memoryless Cg-Methods
(
Qatar University
, 1996 , Article)
Two new CG-methods are proposed in this work for nonlinear unconstrained optimization problems which are considered as memoryless Variable Metric (VM) methods. They are derived for the inexact line searches and evaluated ...
Relation between Quasi-normed Ideals of Entropy Numbers and of Approximation Numbers
(
Qatar University
, 1981 , Article)
Let en(T) and an(T) be the entropy numbers and approximation numbers of operator T between Banach spaces, respectively. Let ?p be the operator ideal defined by
Sp:^TeL;{en(T)^lp}, and Sp be the operator ideal defined ...
