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.

The University of the Free State’s (UFS) first netball team brought the silver medal home this year after they ended second in the University Sport South Africa (USSA) Tournament that was held in Johannesburg. According to Ms Burta de Kock from KovsieSport at the UFS and coach of the team, the team suffered somewhat due to injuries and the fact that eight of their players were newcomers.

In spite of these challenges, six of the UFS players were included in the USSA team. They are Carine Terblanche, Shirolene Smith, Lienke Perold, Anuschka Greeff, Karla Mostert and Anja Zandberg. Karin Venter, also from KovsieSport at the UFS, was appointed as coach of the SA Universities Team.

Kovsie’s netball players also recently played for the Free State U-19 team in a tournament in Mafikeng. The entire team consisted of Kovsies. They won the gold medal by winning all their matches against other regions and provinces. Four of the Kovsie players were also included in the South African U-19 group. They are Karla Mostert, Mione Steinman, Cleopatra Kgoputso and Anuschka Greeff. Anuschka was named as the best goal shooter during the tournament.

The entire Free State U-21 team, which brought home the silver medal after they had lost to Gauteng in the final match, also consisted of Kovsie netball players. Six of these players were included in the South African U-21 team. They are Anja Opperman, Anja Zandberg, Poppie Thethele, Rika Stevenson, Nadia Nieuwoudt and Iselma Parkin. Iselma Parkin was also named the best defender of the tournament and Poppie Thethele the best centre player.
