Remarks On S-Closed Spaces
(
Qatar University
, 1986 , Article)
In this paper, several characterizations for s-closed spaces are obtained using regular semiclosed sets and some sets having two properties of near openness and near closedness in the same time. Images of s-closed spaces ...
The Superimprimitive Subgroups Of The Alternating Group Of Degree 8
(
Qatar University
, 1984 , Article)
A transitive permutation group G is called superimprimitive if it is imprimitive with non-trivial block systems of imprimitivity of lengths all the non-trivial divisors of the degree of G; The superimprimitivity concepts ...
Translation - invariant Positive-definite Generalized Kernels of Infinite Number of Variables
(
Qatar University
, 1981 , Article)
In the theory of spectral analysis of positive-definite j<.ernels, there exist well-developed
methods based on the ideas of Krein connected with the construction of a Hilbert space
by means of a kernel [ 1, 11]. In the ...
On 2n+L-Vertex-Free Graphs
(
Qatar University
, 1983 , Article)
We shall introduce the concepts of pseudoadjacent, pseudocoatraction and pseudoho-momorphism. We shall show, with the help of these concepts, in theorem 2 that every quadrilateral graph V (which is a 4-vertexgraph) has ...
A Special System Of Boundary Value Problems
(
Qatar University
, 1987 , Article)
In this paper we introduce a special system of boundary value problems and give a method for solving it. Then we give a detailed application of this method to a system of boundary value problems of Hilbert type.
On Finite Group Actions On The Solid Klein Bottle
(
Qatar University
, 1989 , Article)
In this paper we classify all G-actions on the solid Klein bottle when G= Z2 and when G= Z^ ® Z2.
On The Behaviour Of The Solutions Of ff …...
(
Qatar University
, 1984 , Article)
The above equation plays an important rote in the geometric theory of functions of a complex variable.
To determine interval estimations for its solutions, an inequality is obtained using the fixed point theorem. Then, ...
A Family Of Nonramified Functions, Defined In Zz<1
(
Qatar University
, 1983 , Article)
In this article a family of nonramified functtions, defined in zz<l, is obtained. It is characterized by an achieved distortion theorem; its Bloch constant and the limit of convexity are determined. Peschl's principle is. ...
Completeness Of Distributive P-Algebras
(
Qatar University
, 1988 , Article)
According to the triple characterization of distributive p-algebras which is given by T. Katrinak, we characterize the completeness of distributive p-algebras.
On Some Shrinkage Techniques For Estimating The Parameters Of Exponential Distribution
(
Qatar University
, 1986 , Article)
A variety of shrinkage methods have been proposed for estimation of some unknown parameter by considering estimators based on a prior guess of the value of the parameter. We compare some of the shrunken estimators for the ...
