Brace $B_{\infty}$ algebras associated with Hopf algebroids

Jiahao Cheng, Zhuo Chen, Yu Qiao

We apply the operadic modeling of brace $B_{\infty}$ algebras, as developed by Gerstenhaber and Voronov, to the context of Hopf algebroids in the sense of Xu. Specifically, we cons…

From smooth dynamical twists to twistors of quantum groupoids

Jiahao Cheng, Zhuo Chen, Yu Qiao +1

Consider a Lie subalgebra $l \subset g$ and an $l$ -invariant open submanifold $V \subset l^{*}$ . We demonstrate that any smooth dynam…
