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.

Prof Frederick Fourie to step down: Statement by the Acting Rector, Prof Teuns Verschoor
2008-09-08

Following the announcement by Prof Frederick Fourie that he is stepping down as vice-chancellor of the University of the Free State (UFS), one cannot help but reflect on the momentous contribution he has made to the development of the UFS.

At the time of his appointment as vice-rector in 1999, the UFS was in a financial crisis. There had been three rounds of staff reductions, there were no funds for equipment or the maintenance of buildings and there was a general mood of despair amongst staff.

With his unique style and talents, and against all odds, as acting rector and as rector from 2003, Prof Fourie succeeded in bringing about a financial turnaround that once again brought hope to the staff of the UFS.

Research improved dramatically, inter alia due to the refurbishment of laboratories and the acquisition of world-class research equipment. General campus infrastructure was significantly upgraded and aesthetically improved, making the physical appearance and quality of the campus and example to other universities.

The university structure was critically analysed in all its dimensions and quality assurance projects were launched to improve the overall package of higher education offerings at the UFS.

Another initiative led to the compilation of a transformation plan that was adopted by the management and the UFS Council and that lays the basis for the years ahead.

Through these and countless other initiatives, Prof Fourie has contributed significantly to the establishment of the UFS as a nationally and internationally recognised higher education institution.

Prof Fourie has laid the foundations for the next period of academic growth and development, the value of which will only be appreciated in its full significance in historical perspective.

The UFS is saddened that the high intensity of change management processes has taken its toll on the rector, but is deeply thankful for the legacy that he leaves.

We wish Prof Fourie many productive years ahead and have faith that his remarkable intellect and capabilities will enable him to make many more contributions to the betterment of South African society.
