A geometric analysis of the SIR, SIRS and SIRWS epidemiological models

H Jardón-Kojakhmetov, C Kuehn, A Pugliese… - Nonlinear Analysis: Real …, 2021 - Elsevier
We study fast–slow versions of the SIR, SIRS, and SIRWS epidemiological models. The
multiple time scale behaviour is introduced to account for large differences between some of …

Numerical continuation for a fast-reaction system and its cross-diffusion limit

C Kuehn, C Soresina - SN Partial Differential Equations and Applications, 2020 - Springer
In this paper we investigate the bifurcation structure of the cross-diffusion Shigesada–
Kawasaki–Teramoto model (SKT) in the triangular form and in the weak competition regime …

A Geometric Singular Perturbation approach to epidemic compartmental models

M Sensi - 2021 - iris.unitn.it
We study fast-slow versions of the SIR, SIRS and SIRWS epidemiological models, and of the
SIRS epidemiological model on homogeneous graphs, obtained through the application of …
