Finite Dimensional Pointed Hopf Algebras with Abelian Coradical and Cartan matrices

N. Andruskiewitsch, H-J. Schneider

In a previous work \cite{AS2} we showed how to attach to a pointed Hopf algebra A with coradical $\kΓ$, a braided strictly graded Hopf algebra R in the category $_Γ^Γ\Cal{YD}$ of Y…
