Algebra Seminar

Pointed Hopf algebras of odd dimension and Nichols algebras over solvable groups

Andruskiewitsch

Nicolás Andruskiewitsch (Universidad Nacional de Córdoba) will be speaking in the algebra seminar. We will go out for lunch after the talk---all are welcome to join! When: 12-1pm Friday May 8 Where: Carslaw 175 Title: Pointed Hopf algebras of odd dimension and Nichols algebras over solvable groups Abstract: We classify finite-dimensional Nichols algebras of Yetter-Drinfeld modules with indecomposable support over finite solvable groups in characteristic 0, using a variety of methods including reduction to positive characteristic. As a consequence, all Nichols algebras over groups of odd order are of diagonal type, which allows us to describe all pointed Hopf algebras of odd dimension.
