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.

Statement by the senior leadership of the University of the Free State
2016-02-29

Statement by the senior leadership of the University of the Free State regarding the situation on the Bloemfontein Campus 

All academic and administrative activities on the Bloemfontein and South Campuses of the University of the Free State (UFS) resume on Monday 29 February 2016.

In light of the recent incidents on the Bloemfontein Campus, the university leadership would like to address the understandable concerns of students, staff and the general public. The university obviously respects the rights of individuals to freedom of speech and expression, but notes that these rights are subject to reasonable limitation, and cannot extend to justifying criminal acts.

The Bloemfontein Campus is secure and security measures have been doubled up to ensure the safety of students, staff and public property. The court interdict is in place and will be enacted if required. Unlawful disruptions, including those involving criminal conduct, will not be tolerated.

The university strongly condemns the unlawful and unacceptable conduct by students, protesting outsourced workers, and visitors to its campus during the past week, and in particular the assault on protestors at Xerox Shimla Park on Monday 22 February 2016 during a Varsity Cup rugby match between the FNB Shimlas and FNB Madibaz. The university has started a comprehensive and independent investigation into criminal activities on this campus before, during and after the Xerox Shimla Park events.

The university regrets the destruction of public property and the intimidation of staff and students which led to the shutdown of academic and administrative activities on the Bloemfontein Campus. Extensive investigations are underway to identify the perpetrators who took part in all incidents of disruption and criminal conduct, and urgent steps will be taken against such individuals or organisations in due course.

The university leadership remains deeply concerned about a dangerous and damaging allegation that a lecturer was identified on a widely circulated photograph while assaulting a protestor at the Varsity Cup rugby match on Monday 22 February 2016. The university diligently investigated this allegation and found it to be false; the individual is NOT a member of the UFS staff. A suspect was however identified and evidence handed over to the South African Police Services (SAPS) for urgent action.

It has further come to the attention of the university management that a number of individuals and organisations continue to make blatantly false and defamatory statements on social media platforms with the intention of inciting criminal conduct, threatening individuals, and spreading fear within the university community in order to unsettle the campus. Investigations are at an advanced stage to prosecute individuals and groups involved in such criminal conduct in the social media; both those who post these statements and those who repost or retweet them, are liable under the law.

Should you wish to confirm whether there is any truth attached to a circulated rumour or allegation, please call +27(0)51 401 2911, +27(0)51 401 2634 or send an email to news@ufs.ac.za. Legal steps will be taken against individuals and organisations that persist in circulating such misleading and damaging statements.
    
The UFS urges all individuals who are in possession of evidence or knowledge of any crimes that have been committed on the Bloemfontein Campus in the past week, to come forward with such evidence and information and to call the numbers indicated above or to send an email to news@ufs.ac.za. Any individuals who are in possession of video footage and photographs of the incidents at Xerox Shimla Park, the Equitas Building (formerly known as the CR Swart Building), Thakaneng Bridge, various residences, the Main Building and the grounds in front of the building, are requested to provide such evidence in order to assist with the identification of those involved in criminal acts.

The university leadership remains committed to its duty to act in the best interests of its students and staff and calls on its community and the public to act peacefully at all times and respect the rights of others.
