The theory of C* -algebra is used to develop a connection between the local extreme points and the topology of the spectrum space G.
New switching algorithm for combining new multi-step CG and self-scaling VM algorithms for non-linear optimization
(
Qatar University
, 1997 , Article)
New interleaved CG and self-scaling VM algorithm is presented in this research which combines Al Bayati's self-scaling VM algorithm with another new multi-step CG algorithm with inexact line searches (ILS). In an interleaving ...
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 ...
On estimates of the rate of convergence In the global limit theorems for Homogeneous markov chains
(
Qatar University
, 1997 , Article)
In this paper some estimates are obtained for the remainder term in the limit theorems for the weighted sum of random variables forming a homogeneous Markov chain with arbitrary set of possible states . The achieved results ...

Filtered Dehomogenization Theory For The Micro-structure sheves OY
(
Qatar University
, 1999 , Article)
In this work we study the theory of dehomogenization at the level of filtered sheaves using the micro-structure sheaves. For the sheaf of quantum section the results are still true.

This paper is devoted to study the inverse scattering problem of a generalized Sturm-Liouville equation on the whole line.The solutions of the considered problem and their asymptotic behaviour are presented.The expansion ...
The Adjoint Problem Of A Modified Sturm-Liouville Boundary Value Problem
(
Qatar University
, 1993 , Article)
The authors give the solutions of the eigenvalue equation that is associated with a modified Stum-Liouille problem. The discrete specturm and hence the resolvent will be obtained by means of different types of solutions ...
