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.”

Victory lies beyond the moment

Mokoena learns a new skill at the Learning Festival arranged

For Mokoena it was just a regular day. Another day. Another rush. As a taxi driver you get used to the adrenaline, taking gaps, foot on the accelerator. Alert. Honking hooters. Angry drivers.

Then it came out of nowhere. A stroke. The one side of his body was going numb. What was happening? What about his job? His income? His life?

Fast-forward a few years.

I meet Mokoena at the Learning Festival arranged by the Centre for Community Engagement, in association with Bloemshelter on the University of the Free State’s Bloemfontein Campus. A reserved young man, Mokoena is busy at one of the stands where a range of people from rural communities come to learn new skills. At no cost. They then go back to teach the skills they learnt in their communities. Job creation, that’s the philosophy: as you develop, you need to develop others. 

When I talk to Karen Venter, Head of Service Learning at the Centre for Community Engagement, the stories are overwhelming. “There was the lady who attended 19 workshops in two days. She went back to her community, shared her knowledge and became an entrepreneur helping others take care of themselves.”

New skills
Mokoena is also here to acquire new skills. After his stroke he was told by occupational therapy students about a project that teaches you to build your own house with raw materials. He takes out his cellphone with a sense of pride. Scrolls through some pictures: “This is my house. I built it from all kinds of things, cow manure, bottles, clay, other people’s rubbish.” The pictures show a house in a neat environment. Solid. Proud. A lot of healing came with building the house. Karen explains: “The physical work he was doing, pushing a wheelbarrow and working, but more than that – the knowledge that he could take charge, make a difference, work on a dream – the healing power of a sense of purpose. He became stronger and more confident.”

Victory 
Mokoena walks back to the sewing workshop he was attending before sharing his story. The buzz continues inside the Equitas Building where artisans, entrepreneurs and UFS staff are sharing their skills. Sewing machines hum away and infrequent beeps sound from a table where an excited group of non-scientists have just completed the building of circuits. Faces light up with every beep. Hands raised. Fists clenched. Victory!

But the victory lies beyond the moment. It’s in the confidence, the learning, and the sharing that will be taking place when these people go back to their communities. Some will participate in research projects; others will benefit from curricular requirements leading students into distant communities, and others will be hosting workshops at the next Learning Festival. 

And there will be more great stories. Like Mokoena’s.
