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 withdraws interdict against SASCO and ANCYL

2003-11-25

The Rector and Vice-Chancellor of the University of the Free State, Prof Frederick Fourie, announced today that a court order against the South African Students Congress (SASCO) and the ANC Youth League (ANCYL) had been withdrawn.

The withdrawal of the court order follows after a written statement by SASCO and the ANCYL in which they “unconditionally withdraw or retract statements threatening to render the institution ungovernable” and give their “commitment not to proceed with our threats to establish our own democratic SRC and occupy the current SRC offices”.

The UFS management obtained the court order in October after SASCO and the ANCYL refused to accept the outcome of the recent student referendum and SRC elections and threatened to disrupt the campus.

Prof Fourie also welcomed the undertaking by SASCO and the ANCYL to act in accordance with the prescribed procedures to resolve any grievance that the organisations may have, saying the UFS management remains committed to a constructive dialogue with all student organisations to manage a campus of diversity, tolerance and non-racialism.

In September students voted in a referendum to test support for a system of proportional representation (PR) for the SRC. A vast majority of students voted against the PR system, a system favoured by SASCO and the ANCYL..

Following allegations of fraud in the referendum, the UFS management asked the auditing firm PriceWaterhouseCoopers to conduct an independent audit of the ballot papers.

The auditors found that a total of 180 ballot papers out of 3513 – only 5.12% - of the votes cast - appeared to have been altered by means of erasing and then changing the student number.

According to the auditors, with all potentially altered and suspicious ballot papers excluded, a huge majority of 60,8% of students voted against the proportional representation system.

A few days after the referendum, the actual SRC election was held. However, at no stage were there any complaints from any organization about the integrity of the SRC election itself.

Despite this and the findings of the auditors, SASCO and the ANCYL refused to accept the outcome.

Law student Quintin du Plessis was elected SRC president. He welcomed the stance taken by SASCO and the ANCYL to pursue their objectives through the existing structures and said the SRC was always willing to engage with these organisations on issues of student governance.
