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.

UFS cracks down on crime on campus

2006-03-15

A comprehensive plan to step up the security on the Main Campus of the University of the Free State (UFS) in Bloemfontein, was approved by the Executive Management (EM) this week.

“The plan briefly comprises of the introduction of reasonable and affordable measures that will promote a safe campus and working environment,” said Rev Kiepie Jaftha, Chief Director: Community Service at the UFS.

“With the plan we want to try and create a user friendly, but safe campus,” said Rev Jaftha.

The plan is the result of an intensive investigation about campus security done by an EM task team.

The following measures will be implemented immediately in phases:

The five current vehicle entrances and exits will remain (i.e. the gate at Nelson Mandela Avenue, the gate at Roosmaryn, the gate at Agriculture, the Wynand Mouton Avenue gate and the Furstenburg Road gate).

The number of smaller pedestrian gates will be reduced and security at those remaining will be increased.
The fences around the campus will remain, upgraded and patrolled on a daily basis.

The security measures at high risk areas (e.g. the Kovsie Church) will be stepped up and the fences in these areas will be electrified.

Vehicle exit control will be stepped up at the gates by means of a mixture of electronic and compulsory visual security control.

Public areas, streets and footpaths will be patrolled and shrubs and trees will be cut and pruned. The streets, footpaths and buildings will also be lit.

Speed reducing mechanisms will be implemented before and after the security control points at all the gates.
Additional staff will be appointed to facilitate the flow of traffic at the gates.

“Over and above these measures, the EM also approved in principle the installation of electronic equipment at all the entrance gates. This will include the installation of cameras,” said Rev Jaftha.

According to Rev Jaftha the installation of the electronic equipment will be complemented by the compulsory cutting and restarting of engines for all vehicles exiting the gates. The measure has been in force since 1 February 2006.

Last year special measures were put in place to safeguard residences and their inhabitants when security guards were placed at all the ladies residences. These measures will stay in force.

“Regular audits will be done to determine the effectiveness of the strategies and systems. Although crime in and around the campus grounds can never be completely eradicated, we want to strive to create an environment on campus and in the workplace where it can be limited,” he said.
