I am always happy to talk about category theory. If you are interested in category theory feel free to get in touch. Here are some notes that I have been using for teaching category theory in the past.
In this section, I collect notes that I used more recently and intend to update and maintain.
In this section I collect notes that may still be usefull as introductions and for background information.
Coalgebras and Modal Logic. ESSLLI, Helsinki 2001.
An Introduction to Stone Duality. MGS 2004.
Topics in Coalgebra. Copenhagen 2004.
Coalgebras and Their Logics. Logic Colummn, 2006.
Modal Logics are Coalgebraic with Cirstea, Pattinson, Schröder, Venema. BCS, 2008.
I also have notes, from various teaching opportunities that I did not find the time to finish and polish … I put some of them here anyway, partly to motivate myself to take them up again when another opportunity arises.
Incomplete notes on Introduction to Category Theory. MGS 2017. Chapter 1 contains a long series of beginner’s exercises that should be suitable for self study if you have a mentor who can answer questions.
An Introduction to Coalgebra and Automata Theory in Three Short Lectures and Two Long (unfinished) Appendices. MGS 2018.
