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.”

UFS Mandela Day Pledge (pdf)

The University of the Free State (UFS) joined people around the globe in celebration of the fourth annual Nelson Mandela Day. Long-time Madiba confidant, Zelda la Grange, delivered the main address, inspiring the crowd with anecdotes gleaned from her intimate knowledge of the former president.

La Grange felt that the UFS as an institution can contribute greatly towards the upliftment of South African society.

“Your university has become what we hope for in South Africa – a transformed society whose purpose serves the greater good of humanity. Embrace and nurture what you have here under the leadership of Prof Jansen and his team. And influence society consciously, every day, in the same way as Madiba did for every day of the 67 years of his activism, and beyond.”

As UFS Vice-Chancellor and Rector, Prof Jonathan Jansen, aptly put it, the Kovsie celebrations aim to give thanks to Madiba as a ‘model of humanity’ and for what he has done for all South Africans.

Prof Jansen stressed that the importance of Mandela Day cannot be overstated.

"I think it is incredibly important because the real legacy of Nelson Mandela is that of a man who gave everything he had for the struggle to gain our freedom, our democracy and that we can get along as just human beings and not as a skin colour, a religion or as strangers," he said.

Events began with a clean-up operation by UFS volunteers, Zelda la Grange and the Bikers for Mandela Day, the Mangaung Metropolitan Municipality and other sponsors. The team cleaned areas in Heidedal and Manguang before returning to the UFS Bloemfontein Campus.

Kicking off the campus section of the programme, UFS staff and students formed a ‘human chain’ on the Red Square as part of a wider initiative which was the brainchild of Archbishop Emeritus Desmond Tutu – who was the main attraction of the 2012 Mandela Day activities at Kovsies.

The assembled ‘chain’ recited the UFS Mandela Day pledge, whilst snaking around the Red Square and the gardens surrounding the Main Building, before offering interfaith prayers to Madiba in honour of the 67 minutes of selflessness epitomised by Nelson Mandela Day.

To conclude the first part of the celebrations, the No Student Hungry campaign’s patrons, Mrs Grace Jansen and Dr Carin Buys, released symbolic doves and joined the chain in the singing of the national anthem.

Rudi Buys, Dean of Student Affairs, said that the symbolic chain showed the UFS community’s aim to “join together as a country and show our commitment to our people” on the special day.

Mangaung Metropolitan Municipality Executive Mayor, Thabo Manyoni, together with Prof Jansen, welcomed UFS staff and students to the main festivities which centred around a coin-laying ceremony in front of the Main Building. All proceeds of the coin laying are to be contributed towards the NSH. More than R83 000 was raised through the coin-laying ceremony and donations, more than double the amount of 2012.

The jubilant crowd was edged on by OFM presenter, Johrné van Huyssteen, who offered to preside as master of ceremonies free of charge as part of his 67 minutes.

Manyoni stressed that Mandela Day is a celebration and should be regarded as a joyous occasion. He said that Madiba’s ability to take action and inspire change, is the foremost aspect of his legacy, one all South Africans should strive to emulate.

“We should all be the champions in the areas where we are. There can never be another Madiba, but we should all aim to be smaller, better Madibas,” he said.

Zelda la Grange emphasised the life-changing influence Madiba has had on her own life, as well as South Africa in general.

“Mandela Day is a call to action for individuals, for people everywhere, to take responsibility for changing the world into a better place, one small step at a time, just as Mr Mandela did. It is a day of service,” she said.

According to her, certain key characteristics are responsible for Madiba’s vast reverence throughout the world, principles everyone should try to emulate. She mentioned his principles, simplicity, honesty, integrity, discipline and respect for other people even when opinions differ, as the foremost of these qualities.

La Grange also stressed that the goodwill shown on Mandela Day should not be limited to one day in a year, but that we should all strive to live each day according to these principles.
