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.

Forgive and forget? Or remember and retaliate?

2015-10-08

Cover of the novel Kamphoer

Fact and fiction came together at the Bloemfontein Campus recently to discuss the traumatic repercussions of the South African War. The event forms part of a three-year project – headed by Prof Pumla Gobodo-Madikizela (University of the Free State Trauma, Forgiveness, and Reconciliation Studies) – which investigates transgenerational trauma in the aftermath of the South African War.

The discussion explored the theme, ‘Working through the Past: Reflections on the novel Kamphoer’.

Together, Emeritus Prof Chris van der Merwe (University of Cape Town) and the author of the novel, Dr Francois Smith (University of the Free State, Department Afrikaans and Dutch, German and French), engaged in a thought-provoking, insightful conversation, tracing themes of trauma and issues of forgiveness presented in Kamphoer. Prof Van der Merwe and Dr Smith demonstrated how both fiction and historical fact can inform our present, and guide us into the future.

discuss the novel Kamphoer and how the book relates to
current issues of transgenerational trauma.

“On a societal level,” Prof Van der Merwe said, “we need to work through trauma by putting it into words, and putting it into a narrative.” When it comes to historical trauma, should we forgive and forget, though? Or rather remember and retaliate? Neither, proposed Prof Van der Merwe. “What I want to plead for is the difficult challenge: remember and forgive.” But Prof Van der Merwe also pointed out that, although forgiveness blesses both the giver and receiver, it is an ongoing process.

Dr Smith agreed wholeheartedly. “One of the discoveries of my book is that forgiving is a continuous process. It’s not something that gets completed at a particular stage in your life. By the same token, you can’t say that you are ever able to leave the past behind.” These issues of trauma, forgiveness, the past versus the present, remembering and forgetting are all integral questions confronting the main character of the novel, Susan Nel .

They are also questions we, as a nation, are currently confronted with, too.

“At this moment in our society,” Prof Van der Merwe said, “we have enough killers. We have a greater need now for caring nurturers.”
