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 student government elections declared free and fair
2015-09-04

The 2015/2016 Student Representative Council (SRC) elections on the Bloemfontein and Qwaqwa Campuses of the University of the Free State (UFS) have been declared free and fair.

The institutional Independent Election Commission Chairperson, Mandla Ndlangamandla, commended the high level of cooperation displayed by all students who participated in the peaceful and organised elections on the Qwaqwa Campus.

“We are proud to indicate that from the beginning of the election process, there were no incidents of intimidation, disruption, threats, and violence that were reported,” he said.

Announcing the election results at Bloemfontein Campus, the representative of the Electoral Commission of South Africa (IEC), Andrew Ndelele, also confirmed that the commission had ensured that the elections were credible.

Voter turn-out increased at both campuses compared to the previous year. The elections, which took place from Friday 28 August to 1 September 2015, saw 8% and 0.7% increases in votes casted at the Qwaqwa and Bloemfontein Campuses, respectively. 

Paseka Sikhosana, President-elect of the Qwaqwa Campus, commended the unity and orderliness displayed by students: “After the polling stations had closed, we came together and sang in peace”.

Incoming SRC President of the Bloemfontein Campus, Lindokuhle Ntuli, also endorsed the impartiality of the elections, while expressing how humbled he was by the support he received during the campaigning period.
