Not too long ago, I spent a fair amount of time thinking and reading about anomalies. The conclusion I ended up coming to was that anomalies themselves aren’t very complicated. But they relate to an extraordinary number of other topics.

So, in many ways anomalies end up acting as sort of a central glue uniting seemingly disparate topics in quantum field theory. I have a terrible memory for these sorts of things, so I spent some time putting together an annotated graph to describe some of these relationships.

There are two version of the graph, which can be found here and here. The annotations can be seen by scrolling over the nodes and the edges of the graph.
