Sign consistency methods to reason over the transitional behavior of dynamic systems

Motivation

In this series of articles I want to explain how interaction graph models and sign consistency methods are used to model the behavior of dynamical systems. The focus lies on modeling the behavior of biological systems, although the application to artificial systems is possible. In particular, I want to show how certain sign consistency methods work, under which assumption they operate, which biological questions they allow us to answer, and what problems exist. My aim is to be very beginner friendly with lots of examples. OK, let’s dive into it! Here is a table of content that list the covered topics from which you can cherry pick.

This is work in progress! The content is still incomplete and changing.
