Relative Calabi-Yau structures and ice quivers with potential

Bernhard Keller, Junyang Liu

In 2015, Van den Bergh showed that complete -Calabi-Yau algebras over an algebraically closed field of characteristic are equivalent to Ginzburg dg algebras associated with…

Relative cluster categories and Higgs categories with infinite-dimensional morphism spaces

Chris Fraser, Bernhard Keller, Yilin Wu

Cluster algebras *with coefficients* are important since they appear in nature as coordinate algebras of varieties like Grassmannians, double Bruhat cells, unipotent cells, ... . T…

Calabi-Yau structures on Drinfeld quotients and Amiot's conjecture

Bernhard Keller, Junyang Liu

In 2009, Claire Amiot gave a construction of Calabi-Yau structures on Verdier quotients. We sketch how to lift it to the dg setting. We use this construction as an important step i…

A refined multiplication formula for cluster characters

Bernhard Keller, Pierre-Guy Plamondon, Fan Qin

We obtain a multiplication formula for cluster characters on (stably) 2-Calabi-Yau (Frobenius or) triangulated categories. This formula generalizes those known for arbitrary pairs…

The Donovan--Wemyss Conjecture via the Derived Auslander--Iyama Correspondence

Gustavo Jasso, Bernhard Keller, Fernando Muro

We provide an outline of the proof of the Donovan--Wemyss Conjecture in the context of the Homological Minimal Model Program for threefolds. The proof relies on results of August,…

The Derived Auslander-Iyama Correspondence

Gustavo Jasso, Bernhard Keller, Fernando Muro

We work over a perfect field. Recent work of the third-named author established a Derived Auslander Correspondence that relates finite-dimensional self-injective algebras that are…
