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.

Dr Rory Pilossof is a senior lecturer in Economics at the University of the Free State (UFS), a postdoctoral fellow in the International Studies Group at the UFS, and a Research Fellow at the University of Kent in the UK.

He became interested in his research field when he studied land reform and land issues in Zimbabwe for his PhD at the University of Sheffield. From there, his research interests have expanded to look at other issues connected to land, such as whiteness and labour.

Issue of land reform
Dr Pilossof's study field links up with the important issue of land reform in Southern Africa, due to its past colonialism and post-colonial politics of land and land ownership. These intersect with a wide range of labour issues that are pressing in the region. He has a keen interest in elite transitions and changes in economic structure in Southern Africa since the 1960s.

Dr Pilossof was nominated to the South African Young Academy of Science in 2017, and received an NRF Y1 rating during 2017. He is also a member of the Amsterdam-based International Institute for Social History’s ‘Global Collaboratory on the History of Labour Relations’. He is a participant in the Leverhulme Trust-funded initiative Comparative History of Political Engagement in Western and African Societies Programme at the University of Sheffield.

 

Alternative ways of looking at change
Dr Pilossof's primary research focuses on issues of land, labour, and changing social and economic structures in Zimbabwe and South Africa. He is also interested in finding alternative ways of looking at change. To this end, he has studied various newspapers and periodicals in the region.

Currently, he spends most of his research time as part of a three-year British Academy-funded Advanced Newton Fellowship into labour relations and occupational structures. In future, he wants to expand his research in the labour field by looking at labour and migration in the region over the course of the 20th century.
