#### 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 ...

#### Mathematics for future engineers : a study of teaching and learning mathematics in an engineering curriculum.

(2014)

This is a study of teaching and learning in the first mathematics module for engineering
students at a South African university. The theoretical framing of the study is derived from
multiple analytical tools: Bernstein’s ...

#### Normality-like properties, paraconvexity and selections.

(2012)

In 1956, E. Michael proved his famous convex-valued selection theorems for l.s.c. mappings
de ned on spaces with higher separation axioms (paracompact, collectionwise
normal, normal and countably paracompact, normal, and ...

#### Linear codes obtained from 2-modular representations of some finite simple groups.

(2012)

Let F be a finite field of q elements and G be a primitive group on a finite set
. Then
there is a G-action on
, namely a map G
!
, (g; !) 7! !g = g!; satisfying
!gg0 = (gg0)! = g(g0!) for all g; g0 2 G and ...

#### Exploring master teachers' use of visuals as tools in mathematical classrooms.

(2011)

The teaching and learning of mathematics has presented a great challenge for mathematics
educationalists over many decades. Researchers have been searching for new strategies and
techniques for improving the understanding ...

#### A modelling approach for determining the freshwater requirements of estuarine macrophytes.

(1998)

Increased abstraction of water in the catchment results in a reduced or altered pattern of river flow
and this holds serious consequences for the downstream estuarine ecosystem. In South Africa this
is a serious concern ...

#### Amplitude-shape method for the numerical solution of ordinary differential equations.

(1997)

In this work, we present an amplitude-shape method for solving evolution problems described
by partial differential equations. The method is capable of recognizing the special
structure of many evolution problems. ...

#### Polynomial approximations to functions of operators.

(1994)

To solve the linear equation Ax = f, where f is an element of Hilbert space H and A
is a positive definite operator such that the spectrum (T (A) ( [m,M] , we approximate
-1
the inverse operator A by an operator V which ...
