A Space Distributed Model and Its Application for Modeling the COVID-19 Pandemic in Ukraine / Roman Cherniha, Vasyl' Dutka, Vasyl' Davydovych // Symmetry. - 2024. - Vol. 16, Issue 11. - 17 p. - https://doi.org/10.3390/sym161114112073-8994https://doi.org/10.3390/sym16111411https://ekmair.ukma.edu.ua/handle/123456789/33342A space distributed model based on reaction–diffusion equations, which was previously developed, is generalized and applied to COVID-19 pandemic modeling in Ukraine. Theoretical analysis and a wide range of numerical simulations demonstrate that the model adequately describes the second wave of the COVID-19 pandemic in Ukraine. In particular, comparison of the numerical results obtained with the official data shows that the model produces very plausible total numbers of the COVID-19 cases and deaths. An extensive analysis of the impact of the parameters arising from the model is presented as well. It is shown that a well-founded choice of parameters plays a crucial role in the applicability of the model.enepidemiological mathematical modelreaction–diffusion equationsCOVID-19 pandemicnumerical solutionarticleArticle
