SEIR - models: temporal heterogeneity

Date: 2021-01-18

In basic SEIR-models the spreading coefficient beta is considered  to be independent of time. This is however an oversimplification: in case of a more serious epidemic, people change their behaviour and government impose rules in order to (try to) lower the number of contacts and thus beta.
In this video we will develop a phenomenological model that captures the time dependence of beta. We will furthermore show how the resulting solutions change qualitatively.
