Reaction-diffusion equations in mathematical models arising in epidemiology

Abstract

The review is devoted to analysis of mathematical models used for describing epidemic processes. A main focus is done on the models that are based on partial differential equations (PDEs), especially those that were developed and used for the COVID-19 pandemic modelling. Our attention is paid preferable to the studies in which not only results of numerical simulations are presented but analytical results as well. In particular, travelling fronts (waves), exact solutions, estimation of key epidemic parameters of the epidemic models with governing PDEs (typically reaction-diffusion equations) are discussed. The review may serve as a valuable source for researchers and practitioners in the field of mathematical modelling in epidemiology.
