Elliptic surfaces over a genus 1 curve with the pair (l3, l9) of singular fibers.
(
Qatar University
, 2000 , Article)
In this paper we give a classication of all minimal elliptic surfaces (n : E —> C, g(c) = 1) with a section and exactly the pair (L, L)) of singular fibers.
Morphisms Of Affine Schemes And Equivalence Of Categories
(
Qatar University
, 1996 , Article)
In this work we construct the relation between the category R-filt (G(R)-gr) and the category O^ — Filt(O^ — Gr).
The quantum (ungraded) version of this result can be obtained by restricting to parts of zero degree. ...
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 ...

A Problem In Thermoelasticity With Two Relaxation Times For An Infinite Thermoelastic Layer
(
Qatar University
, 1995 , Article)
The problem of a ihcrmoclastic layer of finite thickness and infinite extent is considered within the context of the theory of thcrmoclasticity with two relaxation times. The upper surface of the layer is taken as stress ...
Lumping Processes of Periodic ARMA Processes
(
Qatar University
, 2004 , Article)
In this article various lumping processes are defined for periodic ARMA (PARMA) processes, namely, the forward, the backward and the cyclic lumping processes. The inter-relations between the parameters of these lumping ...
Conditionally Exponential Convex Functions On Locally Compact Groups
