The associated graded algebras of biserial fractional Brauer graph algebras
Jing Guo, Nengqun Li, Yuming Liu
For any finite-dimensional algebra , one can associate a graded algebra (denoted by ) with the radical filtration of . An interesting question is to compare t…
On Dual Algebras of Hopf Algebroids
Jingbang Guo
We study the dual algebras of (discrete) Hopf algebroids. In particular, we understand comodules over a Hopf algebroid as (discrete) modules over its dual algebra.
Langlands branching rule for type B snake modules
Jingmin Guo, Jian-Rong Li, Keyu Wang
We prove that each snake module of the quantum Kac-Moody algebra of type admits a Langlands dual representation, as conjectured by Frenkel and Hernandez (Lett. Math. Ph…
The associated graded algebras of Brauer graph algebras II: infinite representation type
Jing Guo, Yuming Liu, Yu Ye
Let be a Brauer graph and the associated Brauer graph algebra. Denote by the graded algebra associated with the radical filtration of . The question when …
On simple-minded systems over representation-finite self-injective algebras
Jing Guo, Yuming Liu, Yu Ye +1
Let be a representation-finite self-injective algebra over an algebraically closed field . We give a new characterization for an orthogonal system in the stable module categ…
An explicit construction of simple-minded systems over self-injective Nakayama algebras
Jing Guo, Yuming Liu, Yu Ye +1
Recently, we obtained in [7] a new characterization for an orthogonal system to be a simple-minded system in the stable module category of any representation-finite self-injective…
