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.

Standing ovation for the UFS Camerata in St Petersburg, Russia
2013-11-26

The OSM CAMERATA (OSMC), flagship ensemble of the University of the Free State’s Odeion School of Music, received a standing ovation during a gala concert at the 13th International Conservatoire Festival presented on 7 November 2013 in the Glazunov Hall under the baton of Maestro Jan Moritz Onken.

The International Conservatory Festival was founded in 2001 by the St Petersburg Rimsky Korsakov Conservatory and has since then become an annual highlight on the concert calendar of St Petersburg.

For the last thirteen years, the festival has developed as a centre of excellence for artists, lecturers, and music experts who represent higher institutions of music from almost every continent. This forum has introduced more than 200 conservatories internationally, and literally produced hundreds of concerts, master’s classes and lectures. Internationally-acclaimed musicians such as Yuri Temirkanov, Rodion Shchedrin, Saulius Sondeckis, Krzysztof Penderecki, Valery Gergiev, Vasily Sinaisky and Semyon Bychkov, as well as young talented performers on the brink of their international careers, have participated in the festival over the years.

The OSMC presented the artistic director of the festival, Prof Lydia Volcheck, with audio-visual material as an audition and received a formal invitation from Prof Mikhail Gantvarg, Rector of the St Petersburg Rimsky Korsakov Conservatoire, in May 2013. Jan Moritz Onken (who was appointed as the OSMC chief conductor and artistic director for 2012) prepared the ensemble with vigour and discipline. Experienced international OSM alumni and several young international professionals served as mentors throughout the year preceding the event.

The OSMC gave two recitals during the festival – a gala performance in the Glazunov Hall, as well as a concert in the St Petersburg White Hall. For the first concert on 7 November (entitled FOUR CONTINENTS FESTIVAL), the OSMC shared the stage with a piano duo from the Karol Szymanowski Academy of Music (Katowice, Poland), the String Quartet of the Colburn Conservatory of Music (Los Angeles, USA), as well as an ensemble of Japanese Traditional Instruments from the Tokyo University of the Arts (Japan).

After the last reverberating notes of the performance of the Phantom Waltz (a work commissioned by the OSM from the South African composer Hendrik Hofmeyr), a thunderous applause and shouts of bravo exploded! The OSMC responded spontaneously with a kwela improvisation as an encore.
