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 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 ...
