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.

Recently Adv. Beatri Kruger from the Unit for Children’s Rights in the Faculty of Law at the University of the Free State (UFS) invited Adv. John Welch, Head of the Witness Protection Programme in South Africa, to address the Free State Human Trafficking Forum (FHF) on the safe-keeping of victims who are witnesses against human traffickers.

Human trafficking is prevalent in the Free State, especially in Bloemfontein. The Unit for Children’s Rights is one of the founding members of the FHF that was established to take action against and fight the disturbing reality of human trafficking more efficiently.

According to Adv. Kruger the FHF identified the problem of trafficked witnesses being threatened by human trafficker syndicates.

Adv. Welch made some suggestions with regard to the safe-keeping of trafficked victims. He also, with some of the forum members, paid a visit to the areas in Bloemfontein where human trafficking is prevalent as well as to the local shelter for trafficked victims.

Adv. Welch undertook to join forces with the FHF in assisting trafficked victims and the local Witness Protection Programme Office is now a member of the forum.

Since December 2009 members of the FHF managed to disrupt the work of the human trafficking syndicates. “The traffickers have not stopped this inhumane practice but there are indications that they have moved to other buildings in the inner city and even to houses in the suburbs. It was reported to the forum that approximately 27 males suspected of being involved in human trafficking had been arrested, and since they are illegal in the country, they were deported to their countries of origin,” said Adv. Kruger.
