Finite dimensional Nichols algebras over finite cyclic groups
arXiv:1201.2064
Abstract
All finite dimensional Nichols algebras with diagonal type of connected finite dimensional Yetter-Drinfeld modules over finite cyclic group are found. It is proved that finite dimensional Nichols algebra over is a quantum linear space and Nichols algebra of connected Yetter-Drinfeld module over with is infinite dimensional.
