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.

The Faculty of Theology and Religion recently hosted the annual Tutu-Jonker Prestige Lecture Series at the Bloemfontein Campus of the University of the Free State (UFS). The purpose of the lecture series is to address modern-day and pressing social challenges from a theological and religious perspective.

With the theme Religions and reconciliation of conflicting identities, guest speaker and Desmond Tutu Chair on reconciliation at the Faculty of Theology: Vrije Universiteit Amsterdam, Prof Eddy van der Borght, spoke about the reformation in the context of shifting European identity formations.

Reconciliation versus social identity

“My focus is on what the Christian concept of reconciliation means for reconciliation in society,” said Prof Van der Borght. He deliberated the global problem of conflict generated by diverse social identities. He also emphasised that religion has huge resources to contribute towards overcoming conflicting identities.

“The theory is that religions know about reconciliation, while in practice it is much more complicated, because often religions are part of the problem of conflict,” he says. He said religions are often the problem in social cultural identities, especially regarding conflict involving different nations, racial, and ethnic groups.

Honouring prominent theologians Tutu and Jonker

The name Tutu-Jonker originates from the two theologians, Emeritus Archbishop Desmond Tutu and the late Prof Willie Jonker, who are both regarded as prominent theologians known for their emphasis on reconciliation in South Africa. The significance of combining the two names is said to bring together two different theological traditions (Anglican and Reformed), cultural groups, and races.

Prof Fanie Snyman, Dean of the Faculty of Theology and Religion, said, “This will also serve the purpose of a welcoming culture at the faculty, embracing diversity and embodying reconciliation.” Both of these theologians received honorary doctorates in Theology from the UFS.
