UFS researcher publishes the highest-cited Maths paper in the world in 2017
An article by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies received New Hot Paper status from Clarivate Analytics.
An article on Applied Mathematics, published by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies in 2017, was recently named New Hot Paper by Clarivate Analytics.

Hot paper status
Essential Science Indicators (ESI) is a unique and comprehensive compilation of science performance statistics and science trends. Data is based on journal article publication counts and citation data from Clarivate Analytics that enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 1 2000+ journals from around the world, this in-depth analytical tool offers data for ranking papers, scientists, institutions, countries, and journals. 

ESI from Clarivate Analytics is updated every two months. The New Hot Papers, which are papers published in the past two years, are in the top one-tenth of one percent (0.1%) for their field and publication period. Prof Atangana’s paper had the highest cite count in the field of Mathematics. 

His article that received the New Hot Paper status is titled: “The new fractional derivative and application to nonlinear Fisher’s reaction-diffusion equation”.

The concept of fractional differential operators with non-singular kernel has captured the minds of several researchers in the past year due to their wider applicability in almost all fields of science, engineering and technology. The new fractional differential operators have opened new windows to model complex real-world problems that could not be modelled using the Newtonian and the well-known Riemann-Liouville fractional differential operators. 

“These operators are the way forward in modelling real-world problems in all disciplines, as they are able to include into mathematical formulation the effect of memory,” Prof Atangana said.

The Atangana-Baleanu fractional derivative
The professor developed a new fractional differential operator, called the Atangana-Baleanu fractional derivative. This 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.”

 The University of the Free State (UFS) has published a book on Bloemfontein for the first time in 25 years. The book, titled “Spatialities of Urban Change”, is the first South African scholarly account in book form of spatial themes on urban change in a secondary city in South Africa. The book was recently launched on the Main Campus in Bloemfontein.

The editors of the book are Prof. Lochner Marais from the Centre for Development Support and Prof. Gustav Visser from the Department of Geography, both from the UFS. Their co-authors are five Ph.D. students in Development Studies, one Ph.D. student in Geography and one master’s student in Development Studies.

According to Prof. Visser, there is a gap in the market for new perspectives on how cities work and how urban theory can develop. This book will contribute to filling that gap. The book also manages to involve students and their research – giving them the opportunity to have their research published.

The book addresses various aspects of Bloemfontein’s spatiality and issues such as suburbanization and the subsequent decline of the central business district, the city’s tourism potential and the impact of the Volksblad Arts Festival on re-imaging the city as a place that has something to offer any visitor, are discussed among others. Other topics include the suburb Westdene and how diverse spatiality manifests itself at this scale, and white flight from the inner city areas.

“A central theme running through the book is how the urban discourse of Bloemfontein relate to the country’s metropolitan core and conversely to other secondary cities,“ says Prof. Visser.
