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.

Shimlas now second on Varsity Cup log

2015-02-25

After scoring nine tries to none to establish a 57-0 win over the Central University of Technology’s (CUT) Ixias in round three of the 2015 Varsity Cup Rugby Tournament, the UFS Shimlas are now second on the overall log.

Despite thunder showers in Bloemfontein on the evening of Monday 23 February, the match at the CUT Rugby Stadium continued. Shimlas’ Arthur Williams opened the scoreboard early with the first try of the evening, after getting his hands on a loose ball to break through the CUT defense line. Only four minutes later, Shimlas’ flank Gerhard Olivier scored another try. Both of these tries were successfully converted by Niel Marais, putting Shimlas in a 16-0 lead within less than seven minutes.

By halftime, the Shimlas’ lead had increased to 39-0. Daniel Maartens started the second-half scoring for the UFS when he crossed the try line in the 46th minute to secure Shimlas’ seventh try. After another successful conversion kick by Marais, the scoreboard read 47-0.

The match began to lose its spark as handling errors and ill-discipline became the order of the day. CUT were reduced to 14 men for the second time in the match, when Boetie Makethlo was sent to the sin bin in the 75th minute for an infringement at the breakdown, inches away from his try line.

Maartens went over the try line again in the 78th minute, scoring Shimlas’ eighth try in the match and taking his team’s score beyond the 50 mark. Shimlas managed yet another try in the last minute, with Niell Jordaan diving over the try line for old time’s sake.

Although the Shimlas’ 2015 Varsity Cup started off with a 29-29 draw against the University of Pretoria’s Tuks in Bloemfontein, they returned the following week to clinch a 24-0 win against the University of Johannesburg at the UJ Stadium. Apart from Tuks, who is at this stage on top of the log, no team has scored against Shimlas thus far in the 2015 Varsity Cup.

Up next, Shimlas will face the Stellenbosch University’s Maties side at Shimla Park in Bloemfontein for round four of the tournament on Monday 2 March 2015.

Our Player that Rocks: Niell Jordaan
