Cosmology – APM4801 | |||
---|---|---|---|

Honours | NQF level: 8 | Credits: 12 | |

Module presented in English |
Module presented online | ||

Purpose: Cosmology is the study of the physical universe. The module first introduces properties of the visible universe, including concepts such as distance scales, redshift, isotropy and homogeneity. This is followed by a brief survey of the structure and evolution of galaxies and stars. An empirical basis is used to show that the physical universe in its entirety has structure and evolves. The module focuses mainly on big-bang models of the universe and gives a description of both Newtonian cosmology and general relativistic cosmology. The big-bang type of evolution of the universe is followed from its early stages, including neutrino decoupling and the radiation dominated era. This is then pursued through decoupling and the origin of the cosmic microwave background radiation, and into the matter dominated era. The module is concluded with a fairly introductory discussion of observational cosmology. The latter looks at a variety of cosmological observations, all using discreet sources of radiation, to test the validity of models. The module is aimed at students who majored in applied mathematics, physics, or astronomy. |

---|---|---|---|

Honours | NQF level: 8 | Credits: 12 | |

Module presented in English |
Module presented online | ||

Purpose: The concept of optimization, in its various forms, is a very fundamental one with an important role to play in various branches of mathematics and of course also in the application of mathematics in other disciplines such as economics and engineering. The infinite dimensional case of optimization is studied in the calculus of variations and in optimal control theory. This module presents the classical theory of optimization in the finite dimensional situation. The emphasis is on the development of the mathematical theory and techniques of optimization (convex analysis, Lagrange multiplier rules) rather than computational or numerical techniques for finding optimal points. |

Purpose: Partial differential equations (PDE’s) have formed a basis of many mathematical models of chemical, physical and biological problems. More recently, the use of PDE’s has also extended to include the fields of economics and financial forecasting. In this module we study various finite difference methods for the numerical solution of these PDE’s. The efficiency of these methods is then examined by means of theoretical analysis of their consistency, convergence and stability. |

Optimal Control – APM4809 | |||
---|---|---|---|

Honours | Year module | NQF level: 8 | Credits: 12 |

Module presented in English |
Module presented online | ||

Purpose: Systems that evolve in time occur naturally in various fields such as dynamics, economics, medicine and ecology, and modelling the behaviour of such systems provides an important application of mathematics. These systems can be completely deterministic, but often it may be possible to control their behaviour through the application of external controls. The theory of optimal control is concerned with finding the controls which, at minimum cost, either direct the system along a given trajectory or enable it to reach a desired target state. This module introduces some of the basic tools of optimal control. Many applications from various fields are also included, to show how the various ‘maximum principles’ help us find the optimal controls in practice. Contents: Terminology and classifications of optimal control problems. Controllability and reachability. Linear time optimal problem. The Time Optimal Principle. The Pontryagin Maximum Principle. Linear equations with quadratic costs. |

---|---|---|---|

Honours | Year module | NQF level: 8 | Credits: 12 |

Module presented in English |
Module presented online | ||

Purpose: I want to introduce you to a module on Finite Elements. This module will develop the basic mathematical theory of the Finite Element Method (FEM).This method is the most widely used technique for engineering design and mathematical physics. In studying this module the student will obtain a clear knowledge of what the Finite Element Method is, how it works and how to use it to solve boundary-value problems. The Finite Element Method is a general technique for constructing approximate solutions to boundary-value problems. The method involves dividing the domain of the solution into a finite number of sub domains, the finite elements, and using variational concepts to construct an approximation of the solution over the collection of finite elements. |

Purpose: Research in the solvability of PDE’s leads us to a much wider scope. In the realization that alternative methods can be used for proving the existence and uniqueness of solutions of linear and nonlinear PDE’s, a new research area in Applied Mathematics was introduced. The theory of Sobolev Spaces was developed, which turned out to be a suitable setting in which to apply ideas of functional analysis to glean information concerning PDE’s. For this reason I want to introduce you to a module on Applied Functional Analysis. |
