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.<\/jats:p>","DOI":"10.3390\/sym16111411","type":"journal-article","created":{"date-parts":[[2024,10,23]],"date-time":"2024-10-23T04:28:43Z","timestamp":1729657723000},"page":"1411","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Space Distributed Model and Its Application for Modeling the COVID-19 Pandemic in Ukraine"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1733-5240","authenticated-orcid":false,"given":"Roman","family":"Cherniha","sequence":"first","affiliation":[{"name":"School of Mathematical Sciences, University of Nottingham, University Park, Nottingham NG7 2RD, UK"},{"name":"Institute of Mathematics, National Academy of Sciences of Ukraine, 3 Tereshchenkivs\u2019ka Street, 01004 Kyiv, Ukraine"},{"name":"Department of Mathematics, National University of Kyiv-Mohyla Academy, 2 Skovoroda Street, 04070 Kyiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasyl\u2019","family":"Dutka","sequence":"additional","affiliation":[{"name":"Bakul Institute for Superhard Materials, NAS of Ukraine, 2 Avtozavods\u2019ka Street, 04074 Kyiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasyl\u2019","family":"Davydovych","sequence":"additional","affiliation":[{"name":"Institute of Mathematics, National Academy of Sciences of Ukraine, 3 Tereshchenkivs\u2019ka Street, 01004 Kyiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Davydovych, V., Dutka, V., and Cherniha, R.
