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 second welcoming ceremony for Prof Francis Petersen was held at the South Campus of the University of the Free State (UFS) on Thursday, 18 May 2017.  It is one of three welcoming ceremonies during the Inauguration week of the new Vice-Chancellor and Rector.

 “Although we are geographically divided, our three campuses need to work together to accomplish our mission,” said Prof Daniella Coetzee, Principal of the UFS South Campus, who gave a warm welcome to staff, special guests, and students who gathered in the Madiba Arena. Prof Nicky Morgan, Vice-Rector: Operations, introduced Prof Petersen and said: “This is the first time that a ceremony of this nature is celebrated across our three campuses.”

Prof Francis Petersen, UFS Vice-Chancellor and Rector, said: “Always try to think differently. Challenge yourself. Be innovative.” He emphasised the importance of making the output of universities more useful to the society. “We are one university with three campuses. We expect the same level of excellence on all three campuses,” he said.

Among the speakers of the day, was Surprise Manyaiyi, the Vice-President of the Bloemfontein Campus SRC, who said that Prof Petersen is the right person to lead the UFS.

The crowd were entertained through various musical items, including the UFS choir, which left the audience in loud cheers and waving flags.
