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.

Forensic investigation at UFS Computer Services division in final stage of finalisation

2007-02-01

Statement by prof Niel Viljoen, Chief Director: Operations

The case in which possible irregularities were investigated at the University of the Free State’s (UFS) Computer Services Division at the end of 2005, and which led to two Deputy Directors’ compulsory leave pending an investigation, is making good progress and is in the final stage of finalisation.

One of the Deputy Directors resigned unconditionally a day before his disciplinary hearing was to take place. He is one of two staff members who were placed on compulsory leave after an internal investigation ordered by the UFS management indicated possible irregularities in the division.

“As a result of the extent of the case and the involvement of more than one local business, the investigation had a long course,” said Prof Viljoen.

“The Deputy Director who resigned would have appeared before a disciplinary committee with Judge Joos Hefer as chairperson on charges of misconduct, involving more than R500 000,” said Prof Viljoen.

“We are going ahead with the process of criminal prosecution against this person and a docket was opened at the commerce branch of the South African Police Services (SAPS). A civil action to recover damages from him was started,” Prof Viljoen said.

With a couple of exceptions, the internal disciplinary process of the other persons involved in the case is also finalised. “The disciplinary hearing of the Deputy Director, who is still in the service of the UFS’s Computer Services division, is scheduled for May 2007. This person is still on compulsory leave,” Prof Viljoen said.

“To demonstrate our commitment to the enhancement of honest work ethics and to give to personnel and students a mechanism to bring any unethical business practices to the attention of the UFS management, a fraud hotline was installed last year. The hotline is operated 24 hours a day for 365 days of the year by KPMG,” Prof Viljoen said.

Prof Viljoen thanked everyone who was involved in the investigation for their cooperation. This includes staff as well as people from outside the UFS. “We are committed to transparent corporate management. Any possible irregularities will be investigated and if staff or students are found guilty of any irregular behaviour, strict actions would be taken against these persons,” Prof Viljoen said.
