Tim Porter crossed menagerie

Here is a more up-to-date version of the Crossed Menagerie (14 chapters). This version is slightly longer than the one that I have put up before. I will add in later chapters as I become ‘happy’ with them.

There are other versions 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 the most recent version.
