Finite Solvable Groups with 4-Regular Prime Graphs
(African Institute for Mathematical Sciences, Master Thesis, 2013-05-23)
In this research project, we seek to address the problem of deciding which nite simple graph is a
prime graph of a nite group. In particular, we only focus on showing which 4-regular graphs can be
prime graphs of some ...
Spectral analysis of certain groups of isometries on Hardy and Bergman spaces
(Academic Press, 2017-12-15)
Using the similarity theory of semigroups as well as spectral theory, we obtain the resolvents of the generators of strongly continuous groups of isometries on the Hardy and Bergman spaces. These groups are obtained as ...
Some Properties of the Essential Numerical Range on Banach Spaces
(HIKARI Ltd,, 2017)
We study the properties of the essential algebraic numerical range as
well as the essential spatial numerical range for Banach space operators.

Weighted Composition Groups on the Little Bloch Space
(Hindawi, 2020-04-29)
We determine both the semigroup and spectral properties of a group of weighted composition operators on the little Bloch space. It turns out that these are strongly continuous groups of invertible isometries on the Bloch ...
4-Regular prime graphs of nonsolvable groups
(CORNELL UNIVERSITY, 2019-01-11)
Let G be a finite group and cd(G) denote the character degree
set for G. The prime graph ∆(G) is a simple graph whose vertex set consists
of prime divisors of elements in cd(G), denoted ρ(G). Two primes p, q ∈
ρ(G) are ...
A Probabilistic Estimation of the Basic Reproduction Number: A Case of Control Strategy of Pneumonia
(cience Publishing Group, 2014)
Deterministic models have been used in the past to understand the epidemiology of infectious diseases, most importantly to estimate the basic reproduction number, Ro by using disease parameters. However, the approach ...
Parameter Driven Dynamics of Trypanosomiasis in a Cattle Population
(HIKARI Ltd, 2014)
In this paper we study the disease dynamics of trypanosomiasis in a
cattle population. The compartmental model presented includes the
wild animal population which provides an alternative feeding source
for the tsetse ...
The algebra of smooth functions of rapid descent
(JOOUST, 2009)
A bounded operator with the spectrum lying in a compact set V ⊂
R, has C∞(V ) functional calculus. On the other hand, an operator H acting on
a Hilbert space H, admits a C(R) functional calculus if H is self-adjoint. So ...
Operators with slowly growing resolvents towards the spectrum
(International Journal of Pure and Applied Mathematics, 2009-03)
A closed densely defined operator H, on a Banach space X, whose spectrum is contained in R and satisfies
Effects of Structural Viscoelasticity in Non-Divergence free Deformable Porous Media with Incompressible Constituents
(Global Journal of Pure and Applied Mathematics, 2018)
In this paper, we investigate the importance of structural viscoelasticity in the mechanical
response of deformable porous media with incompressible constituents
under sudden changes in the external applied quasi-static ...
