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 ...
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 ...

On A Kp Class Of Partial Differential Equations Conservation Laws And Solitary Wave Solutions
(
Qatar University
, 1996 , Article)
It is shown that a KP class of partial differential equations possesses an infinite number of conservation laws. In addition, exact and explicit solitary wave solutions are constructed for the KP class of equations, which ...
Inclusion Relation between Two Absolute Summability Methods
(
Qatar University
, 1999 , Article)
In the present paper, the problem of inclusion of the absolute method of summability \N,q with that of \N,r has been considered. Nesessary and suffiecient condition for which \N,q I C_ N,r I is established, and non-trivial ...
Diagonalizable Indefinite Integral Quadratic Forms
(
Qatar University
, 1991 , Article)
This paper deals with some special cases on Hasse's principle about the diagonalization of Z-lattices L of indefinite regular guadratic forms over Q. It is asserted that for some specific values of a certain set D of ...
Diffusion Problems Arising In Mathematical Biology 2
(
Qatar University
, 1996 , Article)
In this paper we consider long range diffusion, examine the local behavior of epidemics in Lp'q. In section 1 of chapter 2 we develop a model, the long range diffusion pressure in planktonic patchiness and then in secion ...
A Class Of Functions Stronger Than M-Precontinuity, Preirresolute And A-Functions
(
Qatar University
, 1990 , Article)
We propose a definition for a new class of functions that may be stronger than the previous types. Some of its characterizations, connections with known ones and the effect of them on some topological spaces are studied .
