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 sets deadline for applications
2006-11-07

The University of the Free State (UFS) calls on all prospective students wishing to study at the UFS in 2007 to submit their applications for admission by no later than 30 November 2006. 
 
“This applies to first-time entering first-year students and senior students who have interrupted their studies for at least one year,” said Mr Vernon Collett, Registrar: Academic Student Services at the UFS.
 
According to Mr Collett students whose applications for admission are received after 30 November 2006 and until 15 January 2007 will be accepted subject to the availability of place on the programme they applied for. 
 
“No applications of transfer students from other tertiary institutions who wish to continue their studies at the UFS will be accepted after 31 October 2006. After 5 January 2007 no applications will be accepted from prospective students with conditional exemptions,” said Mr Collett.
 
Prospective students who want to apply must pay a non-refundable fee of R120 into a designated account, which will be provided when the application form is sent to them. 
 
The signed application form must be accompanied by a certified copy of the prospective student’s identity document or passport and a proof of payment of the application fee. The application form of a minor must be signed by his/her parent or guardian and the field of study should be clearly indicated.
 
“More than 25 000 students are registered at the UFS Main Campus for the 2006 academic year. We expect a considerable number of applications and foresee that our numbers for next year will be similar to what it is now,” said Mr Collett.
 
First-time entering first-year students on the Main Campus will be welcomed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie, on 13 January 2007 at 11:00 in the Callie Human Centre.
 
The registration of first-time entering first-year students will commence on 16 January 2007 and that of senior students on 22 January 2007 at the Callie Human Centre according to a programme. 
 
Students who applied for admission after 30 November 2006 and are accepted can register from 5 February 2007. 
 
Lectures will commence on 5 February 2007 and the registration process will end on 9 February 2007.
 
Prospective students who want to apply for admission or who have any enquiries can call (051) 401-3000 or visit the UFS web site at www.uovs.ac.za.
