Chaos Kept at Bay is also Ill People’s Hope

If disease is chaos, the mathematical methods of resolving irregular processes within the body support the healing process. Two mathematicians of the Bolyai Institute, University of Szeged (SZTE) are able to tame chaos.


“Some behaviours determined by simple rules, which nevertheless appear to be complex, irregular and random may occur in many areas, such as in the atmosphere, in the flow of liquids, but even in the movements of certain heavenly bodies as well as in our bodies: a behaviour that we call chaotic dynamics. A more thorough understanding of chaos has been the subject of intensive mathematical research since the second half of the last century,” started his explanation Gergely Röst, mathematician.


Gergely Röst, an associate professor at the Bolyai Institute, Faculty of Science and Informatics, University of Szeged, who currently works at Oxford University, researches interdisciplinary life and health sciences based on mathematical methods. He published an article with Gábor Kiss, his colleague from Szeged, who returned from Bristol University in 2014, in an interdisciplinary journal Chaos in the beginning of 2018, which answers the question of how chaos can be kept at bay.


“The Mackey-Glass equation presented in 1977 is used for the mathematical description of physiological regulatory processes, which also reveals the chaotic behaviour behind various bodily abnormalities. Various variants of the equation have successfully been used for different purposes, among others to better understand and treat various types of abnormalities of the hematopoietic system, the cardiovascular system and the nervous system. This is one of the key elements of more complex models in several cases,” explains Gergely Röst.

In many cases, chaotic behaviour is undesirable, so it is important to understand ways to tame the chaos. The gist of the Röst-Kiss idea is to force all solutions into a special domain of the phase space where chaotic behaviour cannot occur. This way, they have succeeded in transforming chaotic behaviour into regular periodic motion or equilibrium with several different mechanisms.


“If the parameters that cause irregularities are changed in the right way, the whole system can be made regular. This can also help us understand and treat abnormal changes in the body,” describes Gábor Kiss the practical importance of the mathematical method.

SZTE Experience

Nikki - Faculty of Health Sciences and Social Studies

My name is Nikki and I am from Iran. Currently I am a second year student studying Physiotherapy at the University of Szeged. I really like the Environment of Szeged as it is a true University City where you can meet people from around the world. I consider Szeged as my second home since I have established my own path here and I have a lot of friends who make me feel home. The reason why I came to Szeged is because I was informed by one of my friends about the fact that the University degrees are EU accredited and will help me to reach my goals and open doors for future job opportunities. Once I have obtained my degree, I would like to stay in Hungary and pursue a post graduate program. Later on I will seize the opportunity to gain some job experience in my field here in Hungary before I hold my ground in Europe.

Tamerlan Mendybayev – Faculty of Agriculture

My name is Tamerlan Mendybayev. I am from capital of Kazakhstan, Nur-Sultan. Currently I am first year student at the Faculty of Agriculture. I chose the University of Szeged as my study destination for several reasons: firstly, it is a well-known applied science institution in Europe and the best in Hungary. Secondly, the program is designed with a significant focus on the developing practical skills of the students and there is a University pilot farm where students keen their skills and implement their knowledge in practice. Undoubtedly, University of Szeged is a place where students become professionals in their academic field.
