Enveloping algebras of double Poisson-Ore extensions
Jiafeng Lü, Sei-Qwon Oh, Xingting Wang +1
It is proved that the Poisson enveloping algebra of a double Poisson-Ore extension is an iterated double Ore extension. As an application, properties that are preserved under itera…

Calabi-Yau Nichols algebras of Hecke type
Xiaolan Yu, Yinhuo Zhang
Let be a Nichols algebra of Hecke type. In this paper, we show that if is Noetherian and of finite global dimension, then has a rigid dualizing complex. We then give a…

Ext algebra of Nichols algebras of type
Xiaolan Yu, Yinhuo Zhang
We give the full structure of the Ext algebra of a Nichols algebra of type by using the Hochschild-Serre spectral sequence. As an application, we show that the pointed Hopf a…
