Krein's method for solving the integral equation of the first kind With logarithmic kernel
(
Qatar University
, 1993 , Article)
Consider the Fredholm's integral equation of the first kind with logarithmic kernel K(IXI) = (- In Ixl. The aim of this paper is to establish the equivalence of Krein's method of solving the equation with the following ...
Collineations Of Polar Spaces
(
Qatar University
, 1990 , Article)
In this paper we consider general embeddable polar spaces with Witt index at least three.
If π : S( ξ) —> S( ξ’) be a thick collineation between polar spaces with i( ξ) =i( ξ’) ≥3. Then there exists a place Ø: k—> k' U ...
Approximating the Distribution of Quadratic Forms Using Orthogonal Polynomials
(
Qatar University
, 1999 , Article)
In this paper we propose some techniques to approximate the distribution of quadratic forms in normal random variables. The first two techniques will be based on orthogonal polynomials, namely; the Hermitte and Laguerre ...
Two Forms Of The Backlund Transformation Of A Third Order Differential Equation
(
Qatar University
, 1996 , Article)
Two explicit forms of Backlund transformation of third order dispersive differential equation are derived. The method of derivation depends on the use of a transformation that couples the equation with its modified one.
The Backlund Transformation Of A Kp-Like Class Of Nonlinear Partial Differential Equations
(
Qatar University
, 1996 , Article)
The Backlund transformation of a class that behaves in a manner similar to that of the Kadometsev-Petviashli is derived via the use of a transformation that couples this class with a modified given class of the same order. ...
Krein's Method For Singular Mixed Problems
(
Qatar University
, 1993 , Article)
In this paper, the spectral relations of the Fredholm integral equation of the first kind for the mixed problems with singular kernel are obtained.
A Numerical Solution For The Bending Of A Plate Using The Boundary Element Method
(
Qatar University
, 1992 , Article)
In this paper the numercial solution for the bending of a plate is considered. The method used is called the Boundary Element Method (BEM). The BEM is a numerical method based on the boundary integral equation formulation ...
Homomorphisms And Subalgebras Of Ms-Algebras
(
Qatar University
, 1995 , Article)
According to the characterization of MS-algcbras from the subvaricty Kj by mean of the triple construction, we characterize the homomorphisms and the subalgebras of the MS-algcbras. Also, we solve the "Fill-in" problem for ...
Explicit Forms of Conservation Laws of a Class of Differential Equations
(
Qatar University
, 1994 , Article)
Explicit forms of conservation laws of a class of nonlinear partial differential equations are derived; firstly from BScklund transformation and secondly from the. fundamental equations of the corresponding inverse method.
S — Compactness Via Ideals
(
Qatar University
, 1991 , Article)
Compactness modulo as an ideal has not been widely studied. Many new sorts of weak compactness have been introduced to topological spaces in the last twenty years but have not been studied using ideals. So, the main aim ...
