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.

Pre-story: Inauguration of Prof F Petersen as 14th Rector of the UFS
2017-05-08

“At the UFS, we want to produce graduates for the world, and we need to ensure that we use our knowledge to uplift society”
— Prof Francis Petersen, 14th Rector of the University of the Free State (UFS)

This week marks the first stage of the official welcoming and inauguration of Prof Francis Petersen as the 14th Rector of the UFS, who assumed his duties on 1 April 2017. 

Proceedings will commence on our Qwaqwa Campus, with a function at which the community is to welcome the incoming Vice-Chancellor and Rector. The event on Thursday 11 May 2017 is expected to attract a wide spectrum of community leaders in the area. Speakers to welcome Prof Petersen will include representatives from the two trade unions, National Health Education and Allied Workers Union (Nehawu) and UVPERSU, as well as representatives from the Student Representative Council (SRC), Thabo Mofutsanyana Education District, and the House of Traditional Leaders.

On Thursday 18 May 2017, the South Campus in Bloemfontein hosts a welcoming ceremony for the new Vice-Chancellor and Rector, including a number of vocal performances and messages from various campus stakeholders. On Thursday afternoon, the Institute for Reconciliation and Social Justice (IRSJ) will also facilitate a panel discussion in the Albert Wessels Auditorium (AWO) on the Bloemfontein Campus.

The inauguration proceedings culminate in an event in the Callie Human Centre on Friday 19 May 2017 at the Bloemfontein Campus, with number of performances by musicians and school choirs to further embellish the function. Key stakeholders will also have the opportunity to convey their messages of welcome to Prof Petersen. The formal inauguration ceremony will take place on the Bloemfontein Campus on the same day.

As the above events take place, this article will be updated with the most recent photographs and other information.
