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…

Lifting of Quantum Linear Spaces and Pointed Hopf Algebras of order p^3
N. Andruskiewitsch, H. -J. Schneider
We propose the following principle to study pointed Hopf algebras, or more generally, Hopf algebras whose coradical is a Hopf subalgebra. Given such a Hopf algebra A, consider its…
