Prof Abdon Antangana
Prof Abdon Atangana, a Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS) and South Africa’s top-ranked scientist in Mathematics, wants to prepare the next generation of African professors.

A new book written by Prof Abdon Atangana, Professor of Applied Mathematics at the Institute for Groundwater Studies at the University of the Free State (UFS), in collaboration with one of his students, on the flow of groundwater, suggests several new and modified models to better predict anomalous behaviours of the flow and the movement of pollution within complex geological formations.

Mathematical Analysis of Groundwater Flow Models is one of two books Prof Atangana published recently that he wrote with his students. The other, Fractional Stochastic Differential Equations: Applications to Covid-19 Modeling, provides a thorough conversation on the underpinnings of COVID-19 spread modelling. He wrote the book with a postdoctoral fellow, Dr Seda Araz Igret from SIIRT University, Turkey. Since 2016 he has published a total number of six books, some of which are still under evaluation by Springer and Elsevier.

Time to prepare next generation of African professors 

This highly cited researcher is excited about collaborating with his students on projects such as these as he feels it is time for him to prepare the way for the next generation of African professors. Prof Atangana is ranked at No 219 in the world rankings and No 1 in South Africa by Research.com, a leading academic platform for researchers. 

According to the platform, which recently released the 2022 Edition of its Ranking of Top 1000 Scientists in the field of Mathematics, the ranking is based on the H-index metric provided by Microsoft Academic and includes only leading scientists with an H-index of at least 30 for academic publications in the field of Mathematics.

“Both books are important for me because they are first-time published books with my own students. There is a time to prepare the way for yourself and a time to prepare ways for the next generation. It is time for me to prepare the way for the next generation of African professors. I wish that the next time this list (https://research.com/scientists-rankings/mathematics/za) [is released] many of my students [will] appear,” says Prof Atangana.

About his book with Dr Igret, he says it presents the dynamic of COVID-19 spread behaviour worldwide. It is noticed that the spread dynamic followed process with nonlocal behaviours, which resemble power law, fading memory, crossover, and stochastic behaviours. Fractional stochastic differential equations are therefore used to model spread behaviours in different parts of the world. 

“The content coverage includes a brief history of COVID-19 spread worldwide from December 2019 to September 2021, followed by statistical analysis of collected data for infected, death and recovery classes,” says Prof Atangana.

Mathematical analysis of Groundwater Flow Models serves as a valuable resource for graduate and PhD students as well as researchers working within the field of groundwater modelling, says Prof Atangana. It includes features such as:
• Modified numerical and analytical methods for solving new and modified models for groundwater flow and transport 
• New flow and transform models for groundwater transport in complex geological formations 
• Examination of fractal and crossover behaviours and their mathematical formulations

Top-ranking scientist 

Prof Atangana was also recently elected as a fellow of The World Academy of Sciences (TWAS) and received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A Hamdan, 2020) on 1 November 2021.

Very recently, he was also ranked No 1 in the world in Mathematics, No 186 in the world in all the fields, and No 1 in Africa in all the fields, according to the Stanford list of 2% single-year table.

He was also named among the top 1% of scientists on the global Clarivate Web of Science list. Fewer than 6 200 or 0.1% of the world’s researchers were included on this list in 2019, 2020 and 2021, with fewer than 10 of the scientists hailing from South Africa. 

“While my name is ranked No 1 in South Africa and No 219 in the world, this shows the impact of my research that has been done since 2013. It is worth noting that this ranking disadvantages younger researchers. For example, I got my first publication in 2013 but the researcher who was ranked No 1 started in 1972. To make the ranking fair, the total H-index should be divided by the number of years of publication. I am very proud to see that despite this disadvantage I am still topping in South Africa and am No 219 in the world.”

On Friday 4 December 2015, Penny Siopis, the well-known Cape Town-based artist, who has been exhibiting her work locally and internationally since 1975, was presented with the 2015 Helgaard Steyn Award and a prize of R 550 000 for her painting entitled Swarm.

A quadrennial award lunch was hosted by the University of the Free State (UFS) Johannes Stegman Gallery in conjunction with the Helgaard Steyn and ABSA Trusts. The Helgaard Steyn Trust was established by the estate of Dr Jan Steyn and was named after his father and his brother who was the last president of the Orange Free State Republic.

Swarm, a 2011 painting using ink and glue on canvas, depicts a swarm of bees in a complex, dynamic, and intense manner. It earned the prestigious award that is dedicated to the promotion of artistic culture based on the adjudicators’ unanimous decision. Angela de Jesus, curator of the Johannes Stegmann Art Gallery at the UFS, Annali Dempsey of the University of Johannesburg Gallery, and Prof John Botha, Associate Professor in Art History at North West University, made up the 2015 panel of judges.

On receiving the award, Siopis thanked the Steyn family, the judges, and the people who nominated her. “I am struck by how fantastic it feels to be acknowledged. It is extraordinary when people are struck by what was your own world and the intensity buzzing in your head.”

According to Prof Botha, “Naturally the work of art is chosen on grounds of artistic merit and in the context of contemporary values with regards to both form and content.”

The award-winning painter studied Fine Arts at Rhodes University and Portsmouth University in United Kingdom. Apart from lecturing Fine Arts at the University of the Witwatersrand, she is an honorary professor at University of Cape Town Michaelis School of Fine Art. She has also taught at the Natal Technicon in Durban.

Siopis has received numerous awards for her work, including a British Council Scholarship, a Merit Award at the 2nd Cape Town Triennial, and the Atelier Award for a residency at the Cité Internationale des Arts in Paris, in addition to the Alexander S Onassis fellowship for research in Greece.
