The members of our research group are researchers of the Department of Analysis and Operations Research of the Institute of Mathematics of BME. Our field of research is the modeling and simulation of processes that can be described by differential equations, or solving other tasks requiring computer modeling (Matlab, Python, Wolfram). The members have extensive experience in research and teaching in this area, which is demonstrated by numerous scientific articles, books and university lecture notes.
