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.

Apocalypticism and mysticism have become two key areas of research that have converged to form the heart of contemporary spirituality. It was with this in mind that leading local and international Bible scholars were invited to a collaborative international conference jointly hosted by the UFS Faculty of Theology and Religion and Yale Divinity School, with the theme Apocalyptic Literature and Mysticism—Investigating a Turn in Recent Apocalyptic Research.

It is perhaps unknown to many that a number of the most profound thinkers, both of Judeo-Christian tradition and other religions in general, were mystics. Their lives and writings speak of a longing for an intimate relationship with God, reflecting on universal existential questions such as understanding our human existence, our creation, and ultimately, the meaning of life.

Apocalypticism, on the other hand, focuses on texts and prophecies describing how an alternative, future world might replace our existing one, a process often cataclysmic in nature, thus, like the mystics, also reflecting on the deeper foundations of human existence and our possible demise.

Traditionally, both have been misunderstood and controversial, but more recent research has revealed their formative role in religious discourses, with many scholars finding growing commonalities between apocalyptic and mystical texts. Moreover, these commonalities help to establish a better understanding of Judeo-Christian traditions, as well as other religions in general.

This hugely successful UFS collaborative effort, as well as others of its kind, contribute to the growth of theology as a discipline, with a positive impact on the broader religious community, the church, and society as a whole in the common desire for a just, equitable, and humane world.
