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 research Chair in Higher Education and Human Development within the Centre for Research on Higher Education and Development (CRHED) at the University of the Free State has secured funding for another five years. It follows a favourable evaluation by the South African Research Chairs Initiative (SARChI) of the research project at the UFS. 

The Director of the Centre, Prof Melanie Walker, says she is delighted by the recognition of the Chair's hard work and significant productivity. “This new round of funding secures the centre and its activities for the next five years.” 

Under the auspices of the Chair, research is conducted on higher education, inequalities and social justice, and how or if universities foster the human capabilities and aspirations of students. In essence, the research studies whether higher education makes a difference to the lives of students, their families and communities. Prof Walker says the Chair's projects look at issues of access, participation and transitions into work, as well as gender, race and social class. The research uses quantitative and qualitative methods and includes a strand of participatory research projects with students.

Prof Walker says through the Chair research project, and the Centre, researchers have developed extensive international links and produced international quality research and publications. “We foster high-quality PhD graduates as a new generation of social science academics.” The Chair has in the first five years produced 10 PhDs and four master’s students. 

The project in the next five years will continue with its focus on higher education and human development research. Prof Walker says all the research efforts seek to contribute to more justice in society and universities and to contribute to debates, policy and practices in higher education and a scholarly knowledge base. 

The Research Chairs Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The assessors looked at features such as the number of students the research entity had trained and how many publications the research team had produced.
