Mathematician makes popular contribution to science Prof Atangana
Prof Atangana is the first African under 40 years of age to be selected as African Academic of Science affiliated in Mathematics. He recently delivered his inaugural lecture and is pictured with Eelco Lukas, Director of the Institute for GroundwaterStudies at the UFS (middle) and Prof Hendri Kroukamp, Acting Vice-Rector: Academic
Prof Abdon Atangana, researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), recently delivered his inaugural lecture on the topic: Understanding God’s Nature with Non-Local Operators.

His research interests are methods and applications of partial and ordinary differential equations, fractional differential equations, perturbation methods, asymptotic methods, iterative methods, and groundwater modelling. Prof Atangana is the founder of the fractional calculus with non-local and non-singular kernels popular in applied mathematics today. He has introduced more than 12 mathematical operators, most of which bear his name (such as the Atangana-Baleanu fractional integral).

He stated: “We will not stop until we change the classical view of doing mathematics. Mathematics is not a subject but a tool given to mankind by God to understand nature. One single mathematical operator cannot portray God’s nature accurately. Therefore the Atangana Baleanu was suggested.”

New weapons

Most physical problems can be expressed in terms of mathematical formulations called differential equations. According to him the differential equation’s aim is to analyse, understand, and predict the future of a physical problem. Prof Atangana introduced the Atangana-Baleanu fractional integral. This brought new weapons into applied mathematics to model complex real-world problems more accurately.

Prof Atangana explained: “The Atangana-Baleanu fractional derivative is able to describe real-world problems with different scales, or problems that change their properties during time and space for instance, the spread of cancer, the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers, and many others. This crossover behaviour is observed in many empirical systems.”

Sudden change

The Atangana-Baleanu fractional derivative is also able to describe physical or biological phenomena, such as a heart attack, the physiological progression from life to death, structural failure in an aeroplane, and many other physical occurrences with sudden change with no steady state.

The new differential and integral operators are nowadays in fashion and are being applied with great success in many fields to model complex natural phenomena. It is believed that the future of modelling complex real-world problems relies on these non-local operators.

UFS apologises for noise disturbance during newcomers' student festival
2010-02-01

Last night (Saturday, 30 January 2010), the University of the Free State (UFS) received various complaints regarding disturbance caused by the noise during a student function that took place at the Rag Farm on the Main Campus.

"I wish to apologise on behalf of the UFS for the inconvenience that residents in the neighbouring residential areas had to suffer during the Newcomers’ Student Festival last night,” said Mr Rudi Buys, Dean of Student Affairs at the UFS.

The function took place to conclude the welcoming period for new students. “Although strict measures applied regarding the staging of the event, amongst others, cut-off times for the performances of the guest artists and die organisation of the Rag Farm to prevent excessive noise, various unexpected factors made this difficult,” said Mr Buys.

One of the factors was the fact the more than double the expected number of spectators attended the event. As a result of this, measures pertaining to crowd control had to be adjusted. “Although we managed to end the event without any incidents, I am truly sorry that we could not bring the disturbance caused to the neighbouring suburbs to an end earlier,” he said.

“We are committed to finding a sustainable solution to those types of challenges that student events at the Rag Farm can offer to the neighbouring residential areas. Therefore we are going to call meetings with residents and community leaders of the residential areas in order to resolve the problems in a collaborative manner,” Mr Buys said.

An internal evaluation of the situation shall also be undertaken in order to rectify any possible errors or shortcomings in the organisation of the Newcomers’ Student Festival, as well as regarding the organisation of future student events.

“We would like to thank residents of the neighbouring residential areas for the exceptional way in which they often exercise patience, show understanding and make allowances for the times when student activities taking place on the Main Campus become demanding. It is therefore important for us to find solutions to challenges in this regard and engage in meaningful cooperation with residents,” said Mr Buys.
