“Hopf algebra actions on rings, I.”
This will be the first of two or three talks. The purpose of these talks is to force me to write some notes that I have been meaning to do for a few months. The first lecture will go at a leisurely pace and will just give some of the background–we will not assume that one knows the definition of a Hopf algebra, for example.
