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…

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…
