Prof Johan Meyer, Senior Professor in the Department of Mathematics and Applied Mathematics, says he is looking forward to learning from others in the field during this collaboration.

What do trees, black holes, earthquakes, and time structures have in common? 

The answer to this question is that these, in one way or the other, form the focus of some of the abstracts delivered during the Annual Congress of the South African Mathematical Society. The society has as its main objective the advancement of mathematics in South Africa. 

The Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), in conjunction with the South African Mathematical Society (SAMS 2021), is hosting the 64th Annual Congress of the society this week (29 November to 1 December 2021).

Prof Johan Meyer, Senior Professor in the department, says the congress, which is being conducted online, is focusing on all aspects of mathematics research, including history and teaching.

Learning from others in the field

The congress, which aims to share the latest research results in mathematics, will be attended by staff and students from universities across South Africa as well as abroad. “Anyone from the public is, of course, welcome to attend or even share their results if they are also involved in mathematics research,” adds Prof Meyer. 

He says that he is looking forward to learning from others in the field during this collaboration. 

The congress will include discussions on more than 120 abstracts, covering category theory, algebra, topology, logic; functional analysis and operator theory; finite groups and combinatorial structures; graph theory and combinatorics; lie symmetries and nonlinear differential equations; and applied and numerical mathematics.

Array of interesting topics presented

“It is important in many areas of science and engineering to predict and to simulate rare, random events, the occurrence of which may have negative or even catastrophic consequences. Examples include internet server overflows, mechanical breakdowns, floods, and financial crashes. Rare events can also have a positive effect, triggering for example chemical reactions or driving genetic evolution via random mutations.” Prof Hugo Touchette from Stellenbosch University will be shedding some light on this interesting topic in his presentation on Predicting and simulating rare events.

Prof Jeandrew Brink, Associate Professor in the Department of Mathematics and Applied Mathematics at the UFS, is presenting a plenary session on the topic Determining the geometry of strong field space-times in spite of tacitly assuming the answer during every measurement. In South Africa, state-of-the art pulsar timing data from the MeerKAT telescope will make a considerable contribution to conducting GR orbital tests. Prof Brink comments on how pulsar timing tests differ from tests using gravitational wave detectors, as well as what we can learn from the framework already employed to perform pulsar timing measurements.

DiMTEC hosts second conference on disaster risk reduction
2009-06-02

 
Dr Anthony Turton, the Director: TouchStone Resources (Pty) Ltd. delivered the opening address at this year’s two-day annual international conference on disaster risk reduction that was presented by the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS).

In his presentation: Sitting on the horns of a dilemma: South Africa and its strategic water supply, he said: “We have simply reached the limit of the water resources in South Africa. On the one hand, we deal with the quantity dilemma in terms of strategic water storage. South Africa and Zimbabwe counts under the top 20 countries in the world in terms of dams built. We can only build about ten more dams.”

“On the other hand, we must deal with quantity. Previous solutions are not future solutions. When water is recycled, hormones such as oestrogen do not disappear. We must become creative and do something else,” he said.

“Science can make a difference. The UFS is well placed in terms of its groundwater research. Universities must invest in the necessary technology because the testing of toxins is essential. We must work in ways to prevent toxins from re-entering the water cycle,” he said.

A number of international speakers such as Dr Fabrice Renaud, Associate Director at the United Nations University’s Institute for Environment and Human Security (UNU-EHS) in Bonn, Germany, Dr Eugene Poolman, Chief Forecaster: Disaster Risk Reduction, South African Weather Service, and Prof. Rob Bragg from the Department of Microbial, Biochemical and Food Biotechnology at the UFS, attended the conference, as well as attendees from 11 different countries.

At the conference were, from the left: Mr Andries Jordaan, Director: DiMTEC at the UFS; Dr Ing Jörn Birkmann, Head of Section: Vulnerability Assessment at the United Nations University’s Institute for Environment and Human Security (UNU-EHS); Dr Anthony Turton, Director: TouchStone Resources (Pty) Ltd.; and Dr Fabrice Renaud, Associate Director: UNU-EHS.
