The next meeting of the seminar of the Mathematical Modeling and Numerical Analysis Department  will be held on September 18, 2024, at 2:00 pm in Room 478 of the Institute of Mathematics and Informatics. A talk on: Singular perturbation theory in epidemic modelling will be delivered by Sara Sottile (University of Bologna, Italy). Abstract: In real world scenarios, the natural phenomena usually evolve on time scales differing by various orders of magnitude. Such separation in time-scales can be found, for example, in the field of chemical oscillations [1], neuroscience [2], ecology [3] or opinion/information spreading [4]. In this context, Geometric Singular Perturbation Theory (GSPT) is a powerful analytical technique which fully exploits the underlying time-scale separation. Epidemiological models also provide a natural fit for these [...]
