Algebraic Approach to Formal Microstructure Sheaves and Formal Quantum Sheaves Over Projective Schemes
(
Qatar University
, 2007 , Article)
The I-adic non-commutative filtrations have crucial applications in the study of Lie algebras and the integral group rings. The I-completion R of a commutative ring R is considered a useful tool in algebraic geometry. Here ...

(
Qatar University
, 2007 , Article)
The initiation and subsequent emergence of lateral roots as secondary roots have been examined in attached and excised roots of Phaseolus vulgaris grown in the absence or presence of indol-3-yl acetic acid (IAA). Treatments ...

Stability of Logistic Autoregressive Model
(
Qatar University
, 2007 , Article)
In this paper we propose a Logistic Autoregressive Model, which is a special case of polynomial Autoregressive Model. The aim of this paper is to study and find the stability conditions of the above model by using a dynamical ...
