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.

The journey does not belong to him alone, but to everyone at KovsieSport.

These were the words of University of the Free State’s (UFS) Wayde van Niekerk, after being named as KovsieSport’s Senior Sportsman of the Year on Wednesday 21 October 2015.

The South African sports star walked away with the award for the third consecutive year, while the Protea netball defender, Karla Mostert, was crowned Senior Sportswoman for the first time.

The Junior Bok, Ox Nche, and the Protea hockey player, Nicole Walraven, were named as Junior Sportsman and Junior Sportswoman of the Year respectively.

Nche represented South Africa’s U20 rugby team this year at the Junior World Championships, played for the Shimlas, and was named the UFS Rugby Club’s best junior player.

Walraven made her debut for South Africa in 2015. She was crowned jointly as the best player at the Provincial U21 tournament, and was also Hockey South Africa’s U21 Player of the Year.

Van Niekerk won gold in the 400 metres at the World Championships in Beijing, becoming only the fourth athlete in history to run the 400 m in less than 44 seconds, and the 200 metres in less than 20 seconds.

“This is precious, and something I will cherish as an athlete: being part of KovsieSport,” he said.

“I arrived at the UFS as a high school boy, started as a junior, and was accepted immediately.”

“I really appreciate everybody who played such a huge part in my life.”

Mostert was named as Player of the Series in the Brutal Fruit series, as well as the Varsity series this year. She was also a star for the Proteas at the World Cup.

“This (the award) is definitely a good way to end my time at Kovsies. This is something one is trying to achieve for years, so it really is a highlight.”

She said it was difficult to describe how much KovsieSport is doing for its athletes, and this was the reason why the UFS achieves so many successes in sport.
