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.

“It is quite easy to write a book in a professional capacity but very difficult to write a book from the heart.”

These were the words of Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), at the launch of Beauty of the Heart: The life and times of Charlotte Mannya Maxeke by Zubeida Jaffer, the current Writer-in-Residence in the Department of Communication Sciences at the UFS.

Perseverance and dedication yields results

Writing a book from the heart is exactly what Jaffer, an award-winning South African journalist and author, set out to do. “When you make the choice to write a story, you need to be very dedicated,” she said.

As this is Jaffer’s third book, one would think that she would have no difficulty in putting pen to paper. On the contrary, she mentioned that it was, in fact, the hardest book she has written because the narrative was not easy to get hold of.

“I wanted Charlotte’s voice to come through, and it took my team and I three years of research and writing,” she said.

Maxeke’s story helps to shape South African society

The three-person panel, hosted by the UFS Sasol Library and SUN MeDIA, and chaired by Prof Jansen, included Jaffer and Dr Thozama April, University of Fort Hare historian who had done her PHD thesis on Maxeke.

Dr April said that Maxeke’s life story is an inspiring one, as it encourages a rethinking of established narratives. “These established narratives have made it possible for historians and researchers to write about the shaping of South African society,” she said.
