Mathematical Conversations

In the absence of a vaccine, isolation is about the only available means to control an epidemic. I would like to share with everyone some things I learned from a project I worked on a few years ago studying the consequences of delays and imperfect isolation. We used a toy model defined by a system of delay differential equations (which gives rise to an infinite dimensional dynamical system) to illustrate some simple points. Some of the ideas may resonate, but I stress that this is NOT specifically about covid-19.
