Prof Tomas Vetrik, Professor in the Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), recently delivered his inaugural lecture on the Bloemfontein Campus.

His research area is graph theory, and he mainly focuses on the degree-diameter problem, graph indices, and metric dimension of graphs.

Research focus

According to Prof Vetrik, mathematics was always his favourite subject in school. He also excelled in maths at university and decided to enrol for a course on graph theory while working on his master’s degree. “I liked it, so I also chose topics from graph theory for my PhD thesis,” he says.

In 2014, at the age of 32, he was appointed Associate Professor at the UFS, after postdoctoral research at the University of KwaZulu-Natal and working at the University of Pretoria. An NRF-rated researcher, he has published close to 75 research papers, a third of that as a single author in some of the most well-known journals in his area. Moreover, he was also research supervisor of three PhD and three master’s students.

International collaborations

In the eight years since his appointment at the UFS, Prof Vetrik has made research visits to universities from 14 different countries that have invited him for research collaborations. 

“I am often overseas. I like working from different places. It is interesting to me, and it helps me to be productive,” says Prof Vetrik, explaining some of the inspiration behind his mathematical ideas.

In the next two years, he would like to study more general mathematical problems beyond his current research area.

He says he is addicted to his research. “It overshadows all my other interests.” 

On the rare occasion when he is not working on his research, Prof Vetrik states that he has to keep himself busy. Unable to relax and do nothing, he likes to do sports of some kind or to travel. 

“I am a simple person. I do not even have a TV at home. I use an old-fashioned mobile phone that cannot access the internet,” he says.

“I realised the importance of not just accessing the policies and political approaches of the leaders of the apartheid regime, but understanding the ideas and world views that informed them. Part of the solution to this was to learn Afrikaans.”

This is according to Dr Jamie Miller, a Postdoctoral Fellow at the University of Pittsburgh, on how he went about getting inside the mind of South Africa’s apartheid regime in order to complete his book, An African Volk: The Apartheid Regime and Its Search for Survival.

The book was launched on 11 October 2016 by the Archive for Contemporary Affairs at the University of the Free State on the Bloemfontein Campus.

Volk refers to the Afrikaner nationalist movement
The book is an ambitious new international history of 1970s apartheid South Africa. It is based on newly declassified documents and oral histories, the majority in Afrikaans, which focus on the regime’s attempts to turn the new political climate to its advantage.

The term volk refers to the Afrikaner nationalist movement, also known as Afrikanerdom. The story of Afrikaner nationalism was the medium through which the regime gained power.

Four main messages from the book

Dr Miller says there are four main messages for his readers. Firstly, the apartheid regime looked to contest and hijack new ideas and norms that formed the postcolonial world, and secondly, that we need to start thinking more seriously about the Cold War in terms of domestic politics, not just geopolitics.

Thirdly, South Africa should be integrated into histories of the global South, and lastly, we should conceptualise the apartheid regime by looking at it not just as an imperial holdover, but also by looking at what was happening in the world in the time period in question.
