Lie symmetries of junction conditions for radiating stars.
(2011)We consider shearfree radiating spherical stars in general relativity. In particular we study the junction condition relating the pressure to the heat flux at the boundary of the star. This is a nonlinear equation in ... 
Mathematical modeling of R5 and X4 HIV : from within host dynamics to the epidemiology of HIV infection.
Most existing models have considered the immunological processes occurring within the host and the epidemiological processes occurring at population level as decoupled systems. We present a new model using continuous ... 
Noether's theorem and first integrals of ordinary differential equations.
(1997)The Lie theory of extended groups is a practical tool in the analysis of differential equations, particularly in the construction of solutions. A formalism of the Lie theory is given and contrasted with Noether's theorem ... 
On free convection and heat transfer in a micropolar fluid flow past a moving semiinfinite plate.
(2012)In this dissertation we investigate free convective heat and mass transfer in micropolar fluid flow past a moving semiinfinite vertical porous plate in the presence of a magnetic field. The aim of this study was to use ... 
On pseudoamenability of C(X;A) for norm irregular banach algebra A.
(2017)Abstract available in PDF file. 
On the geometry of CRmanifolds.
(2015)We study two classes of CRsubmanifolds in Kählerian and cosymplectic manifolds. More precisely, we compare the geometry of CRsubmanifolds of the above two underlying smooth manifolds. We derive expressions relat ing ... 
On the null geometry of quasi generalized CRsubmanifolds of indefinite nearly αSasakian manifolds.
(2017)Generalized CR (GCR)lightlike submanifolds of indefinite almost contact manifolds were introduced by K. L. Duggal and B. Sahin, with the assumption that they are tangent to the structure vector field ξ of the almost ... 
On the theory and examples of group extensions.
(1999)The work described in this dissertation was largely motivated by the aim of producing a survey on the theory of group extensions. From the broad scope of the theory of group extensions we single out two aspects to discuss, ... 
On the theory of the frobenius groups.
(2012)The Frobenius group is an example of a split extension. In this dissertation we study and describe the properties and structure of the group. We also describe the properties and structure of the kernel and complement, ... 
The paradigms of mechanics : a symmetry based approach.
(1996)An overview of the historical developments of the paradigms of classical mechanics, the free particle, oscillator and the Kepler problem, is given ito (in terms of) their conserved quantities. Next, the orbits of the three ... 
Parameters related to fractional domination in graphs.
(1995)The use of characteristic functions to represent wellknown sets in graph theory such as dominating, irredundant, independent, covering and packing sets  leads naturally to fractional versions of these sets and corresponding ... 
Some amenability properties on segal algebras.
(2017)It has been realized that the definition of amenability given by B. E. Johnson in his Classical Memoir of American Mathematical Society in 1972 is too restrictive and does not allow for the development of a rich general ...
