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.

Vice-Chancellor’s Prestige Scholars Programme provides platform for next generation scholars
2015-12-08

Dr Rudo Ngara

“The PSP provides a platform for growth, where scholars get to interact with seniors and peers, giving much needed guidance as to where you are and what the next level of your work should be.” This is how Dr Rudo Ngara —a scholar of the Vice-Chancellor’s Prestige Scholars Programme (PSP)—describes the initiative.

For young scholars, such as Dr Ngara, it can be difficult to generate sustainable funding externally for their research. These researchers are not yet established in networks and collaborations independent of their doctoral supervisors, which makes procuring funding even more challenging. This is where the PSP makes an invaluable contribution.

Through the support of PSP, Dr Ngara was recently awarded a substantial NRF (National Research Fund) grant. Dr Ngara is currently a lecturer in the University of the Free State (UFS) Faculty of Natural and Agricultural Sciences on the Qwaqwa Campus. Her research is especially topical as it investigates how crops—particularly cereals—respond and adapt to a range of abiotic stress factors. These factors include drought, high salinity, and extremely high temperatures. Dr Ngara seeks to develop resilient crops that are better suited to produce under harsh environmental conditions. This research endeavour would have been far more complicated if not for the PSP.

Although the programme is not a funding agency, it does have an excellent record of support towards generating funding from outside sources such as Fulbright, the Commonwealth and, of course, the South African NRF.
