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.

Multilingualism and exclusion to be discussed

Five members of the University of the Free State’s (UFS) Unit for Language Management will be taking part in an international colloquium at the University of Antwerp in Belgium on the theme: “Multilingualism and exclusion – perspectives on language and society” this week.

“During this week’s colloquium, approximately twenty South African and Flemish colleagues will reflect on the complex relationships within multilingual communities, where a variety of factors can contribute to the inclusion or exclusion of individuals or communities. Some of the papers will focus on policy measures (“from above”) with regard to the relative position of languages in a particular state, and the impact of these policy measures on the lives of language users. Others will investigate perceptions and “appropriation” (“from below”) by the same language user. In view of the multiple points of departure, the colloquium should contribute towards a better understanding of the dynamics within multilingual communities,” said Prof. Theo du Plessis, Director of the Unit for Language Management at the UFS.

“To give expression to the theme of multilingualism and exclusion, lectures will be presented in three languages, namely Afrikaans, English and Dutch. Several postgraduate students (from South Africa and Flanders) will also have an opportunity to report on investigations they are conducting within the framework of their master’s degree and doctoral studies,” said Prof. Du Plessis.

The colloquium is a follow-up of an international symposium held at the UFS during April 2006 in which a considerable number of outstanding scholars from various countries participated.

According to Prof. Du Plessis, the proceedings of the symposium held last year will be released in book form as part of the unit’s publication series “Studies in Language Policy in South Africa”, published by Van Schaik Publishers.

This sixth issue in the series entitled: “Multilingualism and Exclusion. Policy, Practice, Prospects” will be released tonight (26 November 2007) by the Permanent Deputy of the Province of Antwerp at a prestigious event during the colloquium. The issue was edited by Prof. Du Plessis, Prof. Pol Cuvelier (University of Antwerp), Dr Michael Meeuwis (University of Ghent) and Ms Lut Teck (Institute for Higher Education and the Arts in Brussels).

The UFS will be represented by Prof. Du Plessis, Prof. Johan Lubbe, Ms Susan Lombaard and Mr Roelof Geyser of the Unit for Language Management, as well as Prof. Jackie Naudé of the Department of Afro-Asiatic Studies, Sign Language and Language Practice. Representatives from the universities of Pretoria, Johannesburg, North West and the Monash University in Johannesburg will also be participating in the colloquium.
