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.”

Forensic investigation at UFS Computer Services division in final stage of finalisation
2007-02-01

Statement by prof Niel Viljoen, Chief Director: Operations  
 
The case in which possible irregularities were investigated at the University of the Free State’s (UFS) Computer Services Division at the end of 2005, and which led to two Deputy Directors’ compulsory leave pending an investigation, is making good progress and is in the final stage of finalisation.
 
One of the Deputy Directors resigned unconditionally a day before his disciplinary hearing was to take place. He is one of two staff members who were placed on compulsory leave after an internal investigation ordered by the UFS management indicated possible irregularities in the division.
 
“As a result of the extent of the case and the involvement of more than one local business, the investigation had a long course,” said Prof Viljoen.
 
“The Deputy Director who resigned would have appeared before a disciplinary committee with Judge Joos Hefer as chairperson on charges of misconduct, involving more than R500 000,” said Prof Viljoen.
 
“We are going ahead with the process of criminal prosecution against this person and a docket was opened at the commerce branch of the South African Police Services (SAPS).  A civil action to recover damages from him was started,” Prof Viljoen said.
 
With a couple of exceptions, the internal disciplinary process of the other persons involved in the case is also finalised. “The disciplinary hearing of the Deputy Director, who is still in the service of the UFS’s Computer Services division, is scheduled for May 2007. This person is still on compulsory leave,” Prof Viljoen said.
 
“To demonstrate our commitment to the enhancement of honest work ethics and to give to personnel and students a mechanism to bring any unethical business practices to the attention of the UFS management, a fraud hotline was installed last year. The hotline is operated 24 hours a day for 365 days of the year by KPMG,” Prof Viljoen said.
 
Prof Viljoen thanked everyone who was involved in the investigation for their cooperation. This includes staff as well as people from outside the UFS.  “We are committed to transparent corporate management. Any possible irregularities will be investigated and if staff or students are found guilty of any irregular behaviour, strict actions would be taken against these persons,” Prof Viljoen said.
