#### Fischer-Clifford theory for split and non-split group extensions.

(2001)

The character table of a finite group provides considerable amount of information about the group, and hence is of great importance in Mathematics as well as in Physical Sciences. Most of the maximal subgroups of the finite ...

#### New analytical stellar models in general relativity.

(2009)

We present new exact solutions to the Einstein and Einstein-Maxwell field equations that model the interior of neutral, charged and radiating stars. Several new classes of solutions in static spherically symmetric interior ...

#### Multi-parameter perturbation analysis of a second grade fluid flow past an oscillating infinite plate.

(2009)

In this dissertation we consider the two dimensional flow of an incompressible and electrically conducting second grade fluid past a vertical porous plate with constant suction. The flow is permeated by a uniform transverse ...

#### Dynamics of dissipative gravitational collapse.

(2008)

In this study we generate the matching conditions for a spherically symmetric radiating star in the presence of shear. Two new exact solutions to the Einstein held equations are presented which model a relativistic radiating ...

#### Applications of symmetry analysis to physically relevant differential equations.

(2005)

We investigate the role of Lie symmetries in generating solutions to differential equations that arise in particular physical systems. We first provide an overview of the Lie analysis and review the relevant symmetry ...

#### Aspects of functional variations of domination in graphs.

(2003)

Let G = (V, E) be a graph. For any real valued function f : V >R and SCV, let f (s) = z ues f(u). The weight of f is defined as f(V). A signed k-subdominating function (signed kSF) of G is defined as a function f : V > ...

#### Stratification and domination in graphs.

(2006)

In a recent manuscript (Stratification and domination in graphs. Discrete Math. 272 (2003), 171-185) a new mathematical framework for studying domination is presented. It is shown that the domination number and many ...

#### Real options : duopoly dynamics with more than one source of randomness.

(2009)

The valuation of real options has been of interest for some time. Recently,
the model has been revised to include more than one source of randomness,
e.g. Paxson and Pinto (2005). In this dissertation, we present a
model ...

#### A classical approach for the analysis of generalized linear mixed models.

(2004)

Generalized linear mixed models (GLMMs) accommodate the study of overdispersion and correlation inherent in hierarchically structured data. These models are an extension of generalized linear models (GLMs) and linear mixed ...

#### On spectral torsion theories.

(2003)

The purpose of this thesis is to investigate how "spect ralness" properties of a torsion theory T on R - Mod are reflected by properties of the ring R and its ring of quotients R,.. The development of "spectral" torsion ...
