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.

UFS forms International Advisory Council
2010-11-09

The University of the Free State (UFS) has established an International Advisory Council (IAC) to advise the leadership of the university on its future positioning strategies, especially in relation to its international ambitions as a place of scholarship and service among the leading universities in the world.

The Council, constituted by Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS, consists of nine high-profile international experts with proven expertise, leadership, influence and experience.

“Since the appointment of Prof. Jansen, the leadership of the university has been revising and aligning several functions as part of a thrust to position the institution to meet 21st century national, regional and international challenges,” says Prof. Aldo Stroebel, Director of International Affairs at the UFS.

The appointment of the IAC is one of the strategies to advise and guide the UFS during the next phase of development and growth.

The university is fortunate to have attracted council members from various spheres of influence who can provide strategic guidance and bring cutting-edge expertise to bear on the policies, strategies and actions plans of the UFS. Among them are Prof. Brenda Gourley, former Vice-Chancellor of the University of Natal (now UKZN); Mr Gert Grobler, SA Ambassador to Japan; and Ms Phumzile Mlambo-Ncquka, Former Deputy-President of South Africa, and Executive Chairperson of the Umlambo Foundation.

The first meeting of the Council will take place from 10-13 November 2010. During this meeting the Council will advise the university leadership on the positioning of the UFS in a global knowledge economy; research excellence; excellence in the scholarship of teaching and learning; student engagement and transformation; and other strategic programmes of focus, including engaged scholarship.

The other Council members are:

- Prof. Joel Samoff: Professor of African Studies, Stanford University, USA (Chairperson)
- Prof Luc D’Haese: Chairperson: University International Committee and Advisor to the Rector, University of Antwerp, Belgium
- Prof. Masafumi Nagao: United Nations University and International Christian University, Japan
- Dr Uri Ofir: International Entrepreneur and Business Development Specialist, Scientech Inc., Switzerland
- Prof. Alice Pell: Vice-Provost International Affairs, Cornell University, USA
- Prof. Akilagpa Sawyerr: Former Secretary-General, Association of African Universities (AAU), Ghana
