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
Hamza Baniata – Faculty of Science and Informatics
I am Hamza Baniata, a first-year student at the Doctoral School of Computer Science, and I am From Jordan. SZTE is continuously supporting research and it has an internationally recognized, highly ranked group of professors. It also offers courses and research topics that are strongly related to my research field; Cloud Computing, Fog Computing and Internet of Things. All of this motivated me to apply to the University/Department of Software Engineering. Szeged is a calm city, full of love and peace. The University of Szeged is similar to the city, which provides the perfect environment for creation and development. Studying at the university requires a high level of effort, commitment and seriousness. Applying to the university and having these characteristics are my two pieces of advice to prospective students. It is very early to define my future now, but I am planning to apply to a research position in my field after graduation and if I had the opportunity, I would love to contribute my effort and knowledge in advancing such a wonderful and respected university.
Ahmad Adha - Faculty of Humanities and Social Sciences
I am Ahmad Adha from Indonesia and currently a 3rd year student in Theoretical Linguistics PhD program. I chose the University of Szeged (SZTE) as my study destination because it is located in the center of the town and it is also the highest ranked university in Hungary. The university staff and the professors were very accommodating and understanding when I decided to change the program that suits my research topic. I am so glad that I can be a part of my current department, and of course SZTE, since it is also the Center of Pragmatic Research which aims to promote advanced linguistic pragmatic research with international collaborations. After graduating, I wish to continue to work in my academic field as a professor and a researcher. My advice for prospective SZTE students is to choose a university with a good academic reputation that fits their passion.
