Finite GK-Dimensional pre-Nichols algebras of super and standard type
Iván Angiono, Emiliano Campagnolo, Guillermo Sanmarco
We prove that finite GK-dimensional pre-Nichols algebras of super and standard type are quotients of the corresponding distinguished pre-Nichols algebras, except when the braiding…
Poisson orders on large quantum groups
Nicolás Andruskiewitsch, Iván Angiono, Milen Yakimov
We develop a Poisson geometric framework for studying the representation theory of all contragredient quantum super groups at roots of unity. This is done in a uniform fashion by t…
On the Hopf algebra structure of the Lusztig quantum divided power algebras
Nicolás Andruskiewitsch, Iván Angiono, Cristian Vay
We study the Hopf algebra structure of Lusztig's quantum groups. First we show that the zero part is the tensor product of the group algebra of a finite abelian group with the enve…
Cohomology rings of finite-dimensional pointed Hopf algebras over abelian groups
Nicolás Andruskiewitsch, Iván Angiono, Julia Pevtsova +1
We show that the cohomology ring of a finite-dimensional complex pointed Hopf algebra with an abelian group of group-like elements is finitely generated. Our strategy has three maj…
