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.

Monkey research attracts international attention

For this year’s Summer School programme, Prof Paul Grobler, from the University of the Free State Department of Genetics focuses on research about the conflict between monkeys and humans in areas where monkeys are regarded as problem animals.

Global expert part of research

This year, Prof Grobler is hosting a group of students and lecturers from the United States of America (USA). The group includes Prof Trudy Turner from the University of Wisconsin-Milwaukee (UWM), a global expert on vervet monkeys. She has been working with the Department of Genetics at the UFS for the past fifteen years, and has also been appointed as an Affiliated Professor in the department.

“The Summer School programme is an opportunity for the American Primatology students to gain practical experience in Africa,” says Prof Grobler.

International interest in Summer School

This year’s Summer School programme involves four lecturers and nine students. The lecturers are from the University of Wisconsin-Milwaukee (UWM), the University of California, Los Angeles (UCLA), Boston University, and Central Washington University.

“We use the genetic information to determine
how monkeys historically infiltrated the
different areas in South Africa.”

This year’s focus is on the genetic structure of the monkeys in South Africa, and research that is being done on the differences and similarities in monkeys from different areas. “We use the genetic information to determine how monkeys historically infiltrated the different areas in South Africa,” says Prof Grobler.

Local nature reserve acting as host

The group will perform field work, including observing monkeys in the Soetdoring Nature Reserve, as well as laboratory work in the department, where they will be assisted by two laboratory technicians.

Two years ago, Prof Grobler and his department tested this idea on a smaller scale, and now they hope to make this a regular event.
