Modelling contagious viral dynamics: a kinetic approach based on mutual utility
arxiv(2023)
摘要
The time evolution of a contagious viral disease is modeled as the dynamic
progression of different classes of populations that interact pairwise, aiming
to improve their condition with respect to a given target. This evolutionary
mechanism is based on binary interactions between agents, designed to enhance
their utility mutually. To achieve this goal, we introduce kinetic equations of
Boltzmann type to describe the time evolution of the probability distributions
of the agent system undergoing binary interactions. The fundamental idea is to
describe these interactions using principles from price theory, particularly by
employing Cobb-Douglas utility functions for the binary exchange and the
Edgeworth box to depict the common exchange area where utility increases for
both agents.
