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 seventh Beyers Naudé Memorial lecture was presented for the first time at the University of the Free State (UFS) this week. This lecture that is presented at a different university each year took place on the Main Campus of the UFS in Bloemfontein this year. Rev. Cedrick Mayson presented the lecture with under the theme: Crafting a legacy.

According to Rev. Mayson more deeply rooted forms of suppression came forward after the democratic elections in 1994. Liberation from apartheid was, according to Mason, very superficial. The poor were still severely suppressed at economic, political, cultural, religious and environmental level. “We have to apply Beyers Naudé’s legacy of liberation in these areas,” Rev. Mayson declared.

“The system according to which the rich become wealthier and the poor become poorer must be replaced by a system where everybody can have enough. This is only possible with the insight of the oppressed.

“The government and the opposition are dominated by people who seek advantage for their own gain. Regardless of democratic slogans and some enlightened individuals’ rules against corruption and violence, we lack the political will to engage in the transformation of the whole world for the good of all earthlings,” said Rev. Mayson.

According to him, consumer culture has become a fine-tuned instrument for keeping people incomplete, shallow and dehumanised.

“Religions are self-centred. Leaders from most of the religious groupings criticised apartheid but they never joined the struggle to assist in demolishing apartheid. It appears as if religious institutions are not able to address the causes of poverty because they themselves are too rich and too powerful,” said Rev. Mayson.

He ended with the following words: “What we need is a leap of faith. Beyers knew that. The world is waiting for people to claim their legacy and to accomplish a post-religious secular spirituality of ubuntu.”

Rev. Mayson is a former Head of Religious Affairs of the ANC. He had also been a former staff member of the Christian Institute before it was banned. Furthermore, he was the Editor of Pro Veritate. Before he retired, he had also been involved in the South African Council of Churches and the World Conference for Peace.

The memorial lecture, a collaborative effort of the UFS and Kagiso Trust, endeavours to involve South Africans in dialogue about issues that affect our nation. This year the lecture was presented at the UFS for the first time and it will take place on the Qwaqwa Campus of the UFS next year.
