Joe Moeller (Feb 07 2025 at 19:42):Someone mentioned to me that they had read some books a while ago and forgot the title/author.
Here's what they do remember: It's about dynamical systems and uses category theory. It's from the 1970's approximately. It was a three-volume set. A big punchline was an adjunction. It only concerned itself with linear dynamical systems.
Does anybody have a clue?
