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 opens centenary complex

2004-10-12

Today, 12 October 2004, the University of the Free State (UFS) opens the Centenary complex on the grounds of the old Reitz dining hall.

Me Edma Pelzer, Director: Physical Resources and Special Projects at the UFS, said the Centenary complex is furnished mainly for personnel and alumni, just as the Thakaneng Bridge was primarily established as gathering place for students.

On 10 March 2004 the UFS management held the first official function in the half completed complex during the unveiling of the memorial stone by the Rector, Prof Frederick Fourie. What made this occasion remarkable is that old President FW Reitz, 81 years earlier, on 10 March 1923, also laid a memorial stone at the same place, said Ms Pelzer. The complex originally existed of the Reitz dining hall, which was named after old president Reitz, a hostel father residence and administration offices. In historical documents about old president Reitz it is mentioned that already as chief judge he campaigned for the establishment of a university in the Free State and later as president he proceeded with this attempt.

With the opening of the Thakaneng-bridge food preparation and -serving at the Reitz dining hall was discontinued. The kitchen and dining facilities became obsolete. With the evacuation of the old student centre replacements for the Bloemfontein- and Anlgo American-rooms were to be found elsewhere on campus. The idea to convert the historical Reitz building complex in an UFS reception and a space for socialising started to exist.

Ms Pelzer said the UFS is committed to treat its history and its old buildings with respect and to utilise it optimally to enhance the strategic objectives of the university. The Centenary complex must communicate the university as an established, quality institution with an interesting history to visitors. It must serve as a home for alumni and as a one stop visiting point for important visitors who do not have time to experience the whole campus.

In the complex provision is made for entertaining and kitchen facilities, a museum where valuable UFS-memorabilia are kept and exhibited, an amfi theatre and an art gallery which would for the first time offer a permanent home for the art collection of the UFS. Venues will accommodate groups from between 15 to 300 persons.

The reception area will be used by the UFS for occasions such as chancellors’ functions, smaller and bigger receptions for the rector, tea parties after graduation ceremonies, openings of conferences and long service awards. The university also plans to rent out the complex for prestige occasions where the UFS personnel and alumni are involved.

The opening of the Centenary complex form part of the Centenary celebrations of this week. Many of this week’s activities will take place in the complex.
