Results in Hungarian
A kutatás fő célja folytonos és diszkrét biológiai, és kémiai modellek tervezése, a meglévők kiterjesztése és elemzése. Kiemelt figyelmet fordítottunk folytonos és diszkrét modellek kvalitatív tulajdonságainak megértésére, és azok matematikai igazolására. A COVID járvány miatt elhúzódó idő lehetőséget adott arra, hogy viszonylag sokrétű kutatásokat folytassunk, amelyek egy részét a szlovén kollégákkal közös munka keretében folytattuk. A kutatásaink legfontosabb eredményei az időközben nagyon aktuálissá vált járványterjedési modellek matematikai vizsgálata, de számos fontos részterületen értünk el eredményeket. Így a járványterjedés folytonos és numerikus modellezésben, a megbízható numerikus modellek előállításában, a modellek stabilitásvizsgálatában, a hatékony prekondicionálási eljárások vizsgálatában, konvergenciagyorsító eljárások kidolgozásába kidolgozásában és mindezek sikeres alkalmazásában. A pályázat keretében 104 publikáció született az NKFIH számára feltüntetett köszönetnyilvánítással, döntő többségében vezető, magas impakt faktorú folyóiratokban. Közöttük három dolgozat a szlovén kollégákkal közös munka eredménye. Emellett számos más nemzetközi együttműködésben is részt vettünk. (Ezeket az éves beszámolókon rendre felsoroltuk.) A pályázati idő alatt száznál is több nemzetközi konferencián vettünk részt, amelynek jelentős részében meghívott plenáris előadók voltunk.
Results in English
The main purpose of the research was to design continuous and discrete biological and chemical models, as well as extend and analyze the existing ones. We paid special attention to understanding the qualitative properties of continuous and discrete models and their mathematical justification. The prolonged time gave us the opportunity to conduct relatively diverse research, some of which was conducted in the framework of joint research with Slovenian colleagues. They are related to the analysis of epidemic spread models, which have become relevant in the meantime, but we have achieved results in many other important subfields as well. Scientifically, we have achieved significant results in the continuous and numerical modeling of the spread of the epidemic, in the production of reliable numerical models, in the stability analysis of models, in the construction and testing of effective preconditioning procedures, etc., and in their successful applications. Within the project, 104 publications were published with acknowledgments to NKFIH, the vast majority of them in leading journals with a high impact factor. Among them, three publications are the result of joint work with Slovenian colleagues. We have also participated in several further international collaborations (listed sequentially in the annual reports). During the application period, we participated in more than a hundred international conferences, in a significant part of which we were invited to plenary speakers.
