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 ...
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 ...
The role and use of sketchpad as a modeling tool in secondary schools.
(2004)
Over the last decade or two, there has been a discernible move to include modeling in the
mathematics curricula in schools. This has come as the result of the demand that society is
making on educational institutions to ...
A simulation modeling approach to aid research into the control of a stalk-borer in the South African Sugar Industry.
(2008)
The control of the African stalk borer Eldana saccharina Walker (Lepidoptera: Pyralidae) in sugarcane fields of KwaZulu-Natal, South Africa has proved problematical. Researchers at the South African Sugarcane Research ...
Fischer-Clifford matrices of the generalized symmetric group and some associated groups.
(2005)
With the classification of finite simple groups having been completed in 1981, recent work in group theory has involved the study of the structures of simple groups. The character tables of maximal subgroups of simple ...
Coagulation-fragmentation dynamics in size and position structured population models.
(2008)
One of the most interesting features of fragmentation models is a possibility to breach
Optimal designs for linear mixed models.
(2004)
The research of this thesis deals with the derivation of optimum designs for linear mixed models. The problem of constructing optimal designs for linear mixed models is very broad. Thus the thesis is mainly focused on the ...
A new approach to ill-posed evolution equations : C-regularized and B- bounded semigroups.
(2001)
The theory of semigroups of linear operators forms an integral part of Functional
Analysis with substantial applications to many fields of the natural sciences. In
this study we are concerned with the application to ...
On the logics of algebra.
(2008)
We present and consider a number of logics that arise naturally from universal algebraic considerations, but which are ‘inherently unalgebraizable’ in the sense of [BP89a], essentially because they have no theo- rems. Of ...
