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.

UFS academic discusses Dutch, Afrikaans and African languages at international conference

Prof Theo du Plessis, Director of the Unit for Language Management at the University of the Free State (UFS), was the main speaker at a colloquium titled “Routes: Where to now? - Een traject van het Nederlands naar het Afrikaans en de Afrikatalen”, which was recently presented by the Province Antwerp in Belgium.

The aim of the colloquium was to discuss the future cooperation in the field of language between the Province Antwerp and South Africa.

The Province Antwerp is already involved with projects in South Africa. One of these projects is the Multilingual Information Development Programme (MIDP), a partnership project between the UFS and the Free State Province that is mainly funded by the Province Antwerp.

The project has been running since 1999 and was recently in the news with the presentation of a symposium on multilingualism and exclusion on the Main Campus of the UFS. It is hoped that the Routes colloquium will indicate new stages on which can be added to the already successful cooperation in the area of language.

Prof Du Plessis’s presentation titled “Nederlands, Afrikaans en die Afrikatale – kan samewerking slaag? Die geval MIDP in die Vrystaat”, investigated the successes that have been made with the MIDP. He discussed two possible approaches to cooperation in the areas of language, that of a sentimentalistic approach against an instrumentalistic approach.

Cooperation in the first approach makes language the aim. In the second approach language is used as a means to a greater aim. According to Prof du Plessis the first approach is driven by a romantisised idea about the relation between the Flemish and Afrikaans speaking people, which may unfortunately polarise the position of Afrikaans in South Africa even further.

He argues that, given the time that we are in, the second approach will deliver more constructive results as language can among others be used for to further democracy in South Africa. This can happen by cooperation in the institutionalising of multilingualism in our society. The more languages are used in education, law and government administration, the more we can be assured a successful democracy.

The Routes colloquium was facilitated by the well-known Flemish radio journalist, Jean-Pierre Rondas. About twenty South African and Flemish language specialists took part in the colloquium. Dr Fritz Kok, outgoing chief executive officer of the ATKV took part in the opening ceremony and Dr Neville Alexander from the University of Cape Town and well-known activist for multilingualism in South Africa was also one of the main speakers.
