Optimal Targeted Lockdowns in a Multi-Group SIR Model
American Economic Review: Insights, 2020 We study targeted lockdowns in a multigroup SIR model where infection, hospitalization, and fatality rates vary between groups—in particular between the “young,” the “middle-aged,” and the “old.” Our model enables a tractable quantitative analysis of ...

A Mathematical Model of Epidemics—A Tutorial for Students
Mathematics, 2020 This is a tutorial for the mathematical model of the spread of epidemic diseases. Beginning with the basic mathematics, we introduce the susceptible-infected-recovered (SIR) model.

A Time-Dependent SIR Model for COVID-19 With Undetectable Infected Persons
IEEE Transactions on Network Science and Engineering, 2020 In this paper, we conduct mathematical and numerical analyses for COVID-19. To predict the trend of COVID-19, we propose a time-dependent SIR model that tracks the transmission and recovering rate at time $t$.

JUE insight: Learning epidemiology by doing: The empirical implications of a Spatial-SIR model with behavioral responses [PDF]
Journal of Urban Economics, 2020 We simulate a spatial behavioral model of the diffusion of an infection to understand the role of geographical characteristics: the number and distribution of outbreaks, population size, density, and agents' movements.

Nodes’ Ranking Model Based on Influence Prediction [PDF]
Jisuanji kexue, 2023 The ranking of nodes’ influence has always been a hot issue in the research area of complex networks.Susceptible-infected-recovered(SIR) model is an ideal nodes’ influence ranking method,which is commonly used to evaluate other nodes’ in-fluence ranking ...

Inhomogeneities in Boltzmann–SIR models
Mathematics and Mechanics of Complex Systems, 2021 We investigate, by means of numerical simulations, the qualitative properties of a Boltzmann equation for three species of particles introduced in previous work, capturing some features of epidemic spread.

Corona-Pandemie: Zukunfts-Überlegungen aus der Sicht epidemiologischer Modellierung
Monitor Versorgungsforschung, 2022 Seit dem Auftreten der Corona-Pandemie bestand weltweit die Frage, wann die Pandemie zu einem Ende kommen würde. Mittlerweile werden solche Hoffnungen von der Befürchtung verdrängt, dass die Infektionskrankheit nicht eliminiert werden kann und endemisch ...

A Novel Fractional-Order Discrete SIR Model for Predicting COVID-19 Behavior
Mathematics, 2022 During the broadcast of Coronavirus across the globe, many mathematicians made several mathematical models. This was, of course, in order to understand the forecast and behavior of this epidemic’s spread precisely.

On the Integrability of the SIR Epidemic Model with Vital Dynamics
Advances in Mathematical Physics, 2020 In this paper, we study the SIR epidemic model with vital dynamics Ṡ=−βSI+μN−S,İ=βSI−γ+μI,Ṙ=γI−μR, from the point of view of integrability. In the case of the death/birth rate μ=0, the SIR model is integrable, and we provide its general solutions by ...
