Indecomposable Representations Of Order Of E6
(
Qatar University
, 1985 , Article)
The extended Dynkin diagram
is a valued graph. We are going to construct a Baechstrom order A associateed to Eg. We prove, by constructions, that the order A of infinite lattice-type but can be listed (tame-type), i.e., ...
Relation between Quasi-normed Ideals of Entropy Numbers and of Approximation Numbers
(
Qatar University
, 1981 , Article)
Let en(T) and an(T) be the entropy numbers and approximation numbers of operator T between Banach spaces, respectively. Let ?p be the operator ideal defined by
Sp:^TeL;{en(T)^lp}, and Sp be the operator ideal defined ...

On Existence Of Two Real Periodic Solutions Of Differential Equations Of Riccati Type
(
Qatar University
, 1986 , Article)
In this paper we consider the two equations
z^z^p^z+r^t), (*) z^z^ptOz+r^t), (••)
where z € C, p, r) and r^ are real, continuous and periodic with period T.
It was shown ...
On Dirichlet Problem With Singular Integral Boundary Condition
(
Qatar University
, 1983 , Article)
In this paper a Dirichlet problem, with singular integral condition, is studied. It is shown that such problem can be reduced to a regular equation which allows us to construct the solution.
A Remark On Proper Left H* — Algebras
(
Qatar University
, 1984 , Article)
W. Ambrose gave the theory of proper H* -algebras and M. Smiley in (2) gave an example of a left H* -algebra which is not a two-sided H* -algebra. Then he modified some of the arguments of Ambrose which yield the structure ...

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 ...
