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 University of the Free State’s Afromontane Research Unit (ARU), which is situated on the Qwaqwa Campus, has the potential to produce some of the world’s best and dynamic young researchers. This is the view shared by Drs Henri Rueff and Reetu Sogani, who were the keynote speakers during the ARU Colloquium hosted at Golden Gate in the Eastern Free State.

Dr Rueff, a geographer and environmental economist from the Universities of Basel and Bern in Switzerland, was referring to no less than ten Qwaqwa Campus postgraduate students who made oral and poster presentations during the inaugural international colloquium.

Colloquium an opportunity to interact
“You have some of the world’s most motivated and highly skilled students who have the courage to stand in front of extremely critical scientists from all over the globe – and that must be commended,” he said.

Dr Reetu Sogani from India said that her first trip to South Africa did not disappoint. “This colloquium was a very good learning experience for me as I had the opportunity to interact with brilliant and young scientists from this part of the world,” she added.

In closing the colloquium, the Senior Director: Research Development, Dr Glen Taylor, committed the UFS to the success of the unit.

“The ARU will strengthen the research output of the campus. But most important of all, it is setting the research agenda for the Qwaqwa Campus, and for the institution at large, to address the challenges that the surrounding mountain communities are faced with,” he said.
