This question already has an answer here:
My motivation for studying Hopf algebras is twofold:
- I'm interested in representation theory and the algebraic structure of group rings.
- I will also take a course on algebraic groups soon and I think it would be helpful to know about Hopf algebras for that.
So I'm looking for a good introductory book on Hopf algebras for self-study and especially for one that has many examples and applications to the two topics mentioned above.
(As for my background, I know abstract algebra, commutative algebra and non-commutative algebra at a basic graduate level, I'm familiar with the basics on representation theory of (mostly finite) groups and category theory (including monoidal and symmetric monoidal, but not braided monoidal categories) and have some rudimentary knowledge of algebraic geometry. I know almost nothing about Lie algebras.)
