Here is a more up-to-date version of the Crossed Menagerie (10 chapters). This version is slightly longer from the one that I have put up before. I have included a new section (in Chapter 2) which looks at the detailed derivation of the automorphism 2-group of a group as corresponding to the , crossed module. I will add in later chapters as I become ‘happy’ with them.
There is a second version available that I prepared for the Lisbon school and workshop. It picks out certain of the same chapters as in the above version but has fairly complete versions of chapters on TQFTs, relative TQFTs and HQFTs. This is ‘work in progress’ but here is a copy of a fairly current version.
