摘要:Nichols algebras are fundamental objects in the classification of finite dimensional pointed Hopf algebras by lifting method of Andruskiewitsch and Schneider. In this talk, the basic method to classify the finite dimensional Nichols algebras of diagonal type will be presented. In principle,we use Weyl groupoids, arithmetic root systems, and Cartan graphs.
