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.

Traditional medicine can play important role in modern drugs discovery
2014-11-11

Indigenous knowledge possesses a great potential to improve science. Making use of this source may lead to advanced technological innovations. This is according to Dr Sechaba Bareetseng, UFS alumnus and Indigenous Knowledge Systems (IKS) Manager at the Council for Scientific and Industrial Research (CSIR).
Dr Bareetseng recently addressed the seventh annual IKS symposium on the Qwaqwa Campus.
“Interfacing indigenous and local knowledge with scientific knowledge has the potential of encouraging and developing inventions, especially in the pharmaceutical industry,” said Dr Bareetseng.
 
“Such interfacing can also enable access to both sets of knowledge without any discrimination whatsoever. It would also encourage co-existence that would improve understanding between the two.”
 
“Traditional medicine,” said Dr Bareetseng, “can play an extended role in modern drugs discovery as it is already happening in Botswana and New Zealand. These two countries are leading this wave of new thinking in as far as drug development is concerned.”
 
Dr Bareetseng also called on established researchers to start embracing the local communities into their research.
 
“Contemporary scientific research demands that local communities must co-author research conducted within and with them by the universities and research institutions. This would help in maintaining trust between the researchers and the communities that feel exploited. Regular feedback would also make communities feel part of the developments,” Dr Bareetseng argued.
 
He further called on the pharmaceutical companies specifically and researchers in general to convert valuable indigenous knowledge and resources into products and services of commercial value. “Plants, the ecosystem and indigenous knowledge must be preserved to provide a source of income for the local communities. Communities must also be protected from foreign exploitation of their intellectual property.”
