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.

Badminton: Kovsies rule the national students championships

2006-04-11

Kovsies' badminton players again, as in the past few years, rule the national students championships currently being presented in Pretoria by TUT and UP.

The men, Chris Dednam, Roelof Dednam, Wiaan Viljoen and Raymond Ronne, had no other serious competition and were left to each other's rivalry. Especially Roelof Dednam performed excellent by surprisingly going through to the finals in beating Viljoen in the singles, and with Elaine Lues also Chris Dednam and Liansa Coetzee in the mixed doubles.

In the absence of Annari Viljoen (injured) and Sone Strauss (retired), the less experienced girls, Liansa Coetzee and Lizl Janse van Rensburg, had to uphold the Kovsie name. They performed excellent by taking third and fourth positions.

In the team competition which now takes place, Kovsies should make a clean sweep.

It is a pity that, through financial restraints, Kovsies players will not in October strengthen the SASSU team to the world student championships in China.

Results of the individual championships:

Men's singles: winner - Chris Dednam (UFS), runner-up - Roelof Dednam (UFS), third - Wiaan Viljoen (UFS), fourth - Raymond Ronne (UFS);

Men's doubles: winners - Chris Dednam / Roelof Dednam (UFS), runners-up- Wiaan Viljoen / Raymond Ronne (UFS);

Women's singles: winner - Kerry-Lee Harrington (KZN), runner-up - Christina English (TUT), third - Liansa Coetzee (UFS), fourth - Liezl Janse van Rensburg (UFS);

Women's doubles: winners - Kerry-Lee Harrington (KZN) / Christina English (TUT), runners-up - Liansa Coetzee (UFS) / Maret Visser (NW), quarter-finals - Elaine Lues / Anel Vorster (UFS), Liezl Janse van Rensburg (UFS) / Sarah Rice (Wits);

Mixed doubles: winners - Andre van Schalkwyk / Christina English (TUT), runners-up - Roelof Dednam / Elaine Lues (UFS), third - Chris Dednam / Liansa Coetzee (UFS), fourth - Wiaan Viljoen / Liezl Janse van Rensburg (UFS).
