Corrigendum: Liftings of the Jordan plane

Liftings of Jordan and super Jordan planes

We classify pointed Hopf algebras with finite Gelfand-Kirillov dimension whose infinitesimal braiding has dimension 2 but is not of diagonal type, or equivalently is a block. These Hopf algebras are new and turn out to be liftings of either a Jordan or a super Jordan plane over a nilpotent-by-finite group.

非半单世界中的提升

Lifting in a non semisimple world

本文研究了非半单世界中 Nichols代数的提升问题，提出了一种推广的bosonization代数，并证明每个提升都是其cocycle变形。
