Observations On Quasi-Uniform Products
(Elsevier Science Bv, 2007)
We prove that any product of quotient maps in the category of quasi-uniform spaces and quasi-uniformly continuous maps is a quotient map. We also show that a quasi-uniformly continuous map from a product of quasi-uniform ...
On The Noncommutative Neutrix Product Of Distributions
(Hindawi Publishing Corporation, 2007)
Let f and g be distributions and let g(n) = (g * delta(n))(x), where delta(n)(x) is a certain sequence converging to the Dirac-delta function delta( x). The noncommutative neutrix product f circle g of f and g is defined ...
On Powers Of The Heaviside Function For Negative Integers
(Academic Press Inc Elsevier Science, 2007)
The distributions (x(+)(r))(-s) and (x(+)(r))_(-s) were defined as the neutrix limit of the sequences ((x(+)(r))(-s))n and ((x(+)(r))_(-s))n respectively for r, s = 1, 2,..., see [J.D. Nicholos, B. Fisher, The distribution ...

Remarks on Separation of Convex Sets, Fixed-Point Theorem, and Applications in Theory of Linear Operators
(Springer International Publishing Ag, 2007)
Some properties of the linear continuous operator and separation of convex subsets are investigated in this paper and a dual space for a subspace of a reflexive Banach space with a strictly convex norm is constructed. Here ...
On Modules And Matrix Rings With Sip-Extending
(Mathematical Soc Rep China, 2007)
In this note we study modules with the property that the intersection of two direct summands is essential in a direct summand (SIP-extending). Amongst other results we show that the class of right SIP-extending modules is ...
Non-Linear And Non-Stationary Modes Of The Lower Branch Of The Incompressible Boundary Layer Flow Due To A Rotating Disk
(Amer Mathematical Soc, 2007)
In this paper a theoretical study is undertaken to investigate the structure of the lower branch neutral stability modes of three-dimensional small disturbances imposed on the incompressible Von Karman's boundary layer ...
Reduced and P.Q.-Baer Modules
(Mathematical Soc Rep China, 2007)
In this paper, we study p.q.-Baer modules and some polynomial extensions of p.q.-Baer modules. In particular, we show: (1) For a reduced module M-R,M-R is ap.p.-moduleiff M-R is a p.q.-Baer module. (2) If M-R is an ...
An Asymptotic Investigation Into The Stabilization Effect Of Suction In The Rotating-Disk Boundary Layer Flow
(Pergamon-Elsevier Science Ltd, 2007)
The suction effects in the three-dimensional boundary layer flow due to a rotating disk are analyzed from the linear stability point of view making use of the asymptotic structure of the suction mean velocity profiles of ...
On Hollow-Lifting Modules
(Mathematical Soc Rep China, 2007)
Let R be any ring and let M be any right R-module. M is called hollow-lifting if every submodule N of M such that M/N is hollow has a coessential submodule that is a direct summand of M. We prove that every amply supplemented ...
Restructuring E-Learning With Ontologies
(Ieee, 2007)
This paper examines the role of ontologies in the e-learning environments. A brief review of various ontologies is discussed in three areas: Learning design, learning content and learner profile. A new perspective for ...
