Maths professor breaks new ground

Atangana's name among top academics in the world

Professor Abdon Atangana is delighted that his name has been added to the list of highly cited mathematic­ians around the world.

Atangana has described his acclaim as “a first step in the decolonisa­tion of science and an indication that Africans can contribute and influence the world of mathematic­s”.

Atangana, a professor from the University of the Free State (UFS), together with a colleague, professor Dumitru Baleanu from Cankaya University in Ankara, Turkey, developed a mathematic­al operator that could be used to show case real world problems arising in many fields of science, mathematic­s, technology and engineerin­g.

Atangana provided new fractional differenti­al operators called AtanganaBa­leanu fractional derivative­s.

“The Atangana-Baleanu fractional derivative­s brought new weapons into applied mathematic­s to model complex realworld problems more accurately.

“These operators have their applicatio­ns to nearly all fields of science, technology and engineerin­g. In physics the derivative of a displaceme­nt of a moving body with respect to time is the speed and the derivative of a speed with respect to time is accelerati­on. In other fields differenti­al operators are used to model the spread of the virus and in the groundwate­r they are used to portray the movement of subsurface water within geological formation. So in general, differenti­al and integral operators are used to showcase real-world problems that arise in all fields,” Atangana said.

Explaining this concept, Atangana said the fractional derivative is able to describe physical or biological phenomena such as a heart attack, the physiologi­cal progressio­n from life to death, structural failure in an aeroplane and many other physical occurrence­s of sudden change, with no steady state.

The two professors developed their differenti­al operators in 2016 when existing operators failed to accurately show some physical problems.

“I am excited to see that an African mathematic­ian is attached to operators used in may fields of science, technology and engineerin­g. I am also the first editor of more than 20 top-tier journals of applied mathematic­s. For me this is a first step in the decolonisa­tion of science, an indication that Africans can contribute and influence the world of mathematic­s,”

Atangana said.

The Atangana-Baleaunu operators has been cited in 351 published and peer reviewed research papers since the first paper was published in 2016.

“This is a very big joy, as one day an

African child will say ‘I am proud to be African’, as these theories were developed by a black African youngster. A big joy to see that, for the first time ever, a black mathematic­ian is added in the list of highly cited mathematic­ians,” Atangana said.
