The associated graded algebras of Brauer graph algebras II: infinite representation type

Jing Guo, Yuming Liu, Yu Ye

Let $G$ be a Brauer graph and $A$ the associated Brauer graph algebra. Denote by $g r (A)$ the graded algebra associated with the radical filtration of $A$ . The question when $g r (A)$ …
