Generalized Airy's- and taylor Integral Functions
(
Qatar University
, 1982 , Article)
In this paper a generalized form of Airy's function has been estimated and an asymptotic expansion for one of its types is obtained. Furthermore, an improved formula could be induced to acquire the asymptotic expansion of ...
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 ...
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 ...
