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.

Student organisation tackles difficult questions in debate

“South Africa is consumed by a monster, namely the lack of critical thinking and dialogue with regard to our problems. Now is the time to make radical changes.” This is according to Nombuso Ndlovu, who spoke at the first debate in a series of Commercio and the UFS Business School.

“Young people are more interested in social gatherings than applying their minds to the problems of South Africa,” she said. Nombuso is the CEO of Commercio.

Commercio is the student organisation in the Faculty of Economic and Management Sciences. Two teams, one positive and one negative, debated the topic: Is South Africa’s current economic direction viable?

What emerged from the debate was that our students are well-aware of what is going on in our economy and that people cannot just sit back and expect government to deliver. Every individual has a responsibility. South Africa has a “democratic deficit” society, a “corruption-stricken economy” and “economic activism” is necessary to get the economy on the right path.

Prof. JP Landman, Visiting Professor at the Business School, economic advisor, analyst, columnist and also managing director of the Aardklop Arts Festival, was the expert panel member. He said the critical issue in South Africa is “how do you distribute wealth while keeping things going?”

“It is fantastic that South Africans have developed a collective repulsiveness for corruption.” People must know what underpins society and where aggression comes from.
