Nonlocal finite difference discretization of a class of renewal equation models for epidemics
MATHEMATICAL BIOSCIENCES AND ENGINEERING(2023)
摘要
In this paper we consider a non-standard discretization to a Volterra integro-differential system which includes a number of age-of-infection models in the literature. The aim is to provide a general framework to analyze the proposed scheme for the numerical solution of a class of problems whose continuous dynamic is well known in the literature and allow a deeper analysis in cases where the theory lacks.
