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.

Students have a responsibility in SA, says Ntuli

You and I have a role to play in building the new South Africa built upon the Constitution of 1996.

These are the words of Lindokuhle Ntuli, President of the Student Representative Council (SRC) on the Bloemfontein Campus of the University of the Free State (UFS). They echo his and the SRC’s message of a “campus for all students, locally and internationally, irrespective of colour.”

Ntuli and Paseka Sikhosana, president of the SRC on the Qwaqwa Campus, were in agreement about their vision for the UFS in 2016.

According to Sikhosana, a well-known slogan accentuates a feeling of uniqueness at the university. “United in diversity. No wonder we say only a Kovsie knows a feeling,” he says.

“As the SRC, we believe that complete transformation on campus is through promoting a non-sexist, non-racial, but democratic student society that acknowledges diversity and change. That further promotes and embraces one student’s difference in terms of culture, tradition, religion, and sexual orientation.”

A new South Africa

Ntuli means students have a responsibility. He referred to a quotation from Frantz Fanon’s book, The Wretched of the Earth, to illustrate this. Fanon was a revolutionary and writer whose works are influential in post-colonial studies. “Every generation has a mission. It is the responsibility of every generation to discover its mission. Once you have discovered it, you have to fulfil it or betray it into relative obscurity,” Ntuli quoted.

According to him, the South African Constitution holds pious promises of a better life for all, and each citizen needs to help to achieve that.

SRC has open door policy 

Ntuli says the UFS remains committed to human embrace, diversity, integration, and human togetherness. He added that the SRC has an open door policy, and will avail itself in helping students.

According to Sikhosana, it is the objective of the SRC to represent the student community in all interactions within the university and externally.

“There is nothing for us, about us, without us students,” he says.
