From 30^th March to 5^th April 2025, as part of the Erasmus+ teaching-stay program, Professor Diblík stayed at the University of Pannonia, Veszprém, Hungary. With this university, our department has had long-term contacts involving both teaching and research. Professor M. Pituk, who works there, has visited our department several times, sharing with us his world-class results. In cooperation with Professor Diblík and Professor G. Szederkényi (Pázmány Péter Catholic University, Budapest, and Institute for Computer Science and Control, Budapest) he has also written a paper published last year in the prestigious journal Automatica.
