Irreducible tensor product modules over the Takiff Lie algebra for
Yu Qiao, Xiaoyu Zhu
In this paper, we construct a class of non-weight modules over the Takiff by taking the tensor products of the irreducible free -mod…

Brace algebras associated with Hopf algebroids
Jiahao Cheng, Zhuo Chen, Yu Qiao
We apply the operadic modeling of brace algebras, as developed by Gerstenhaber and Voronov, to the context of Hopf algebroids in the sense of Xu. Specifically, we cons…

Deformation and -theoretic Index Formulae on Boundary Groupoids
Yu Qiao, Bing Kwan So
Boundary groupoids were introduced by the second author, which can be used to model many analysis problems on singular spaces. In order to investigate index theory on boundary grou…
