Iyama-Solberg correspondence for exact dg categories

Representation Theory 2024-02-12 v2 Category Theory

Abstract

We generalize the notions of dd-cluster tilting pair and dd-Auslander exact dg category to dd-precluster tilting triple and dd-minimal Auslander--Gorenstein exact dg category. We give a bijection between equivalence classes of dd-precluster tilting triples and equivalence classes of dd-minimal Auslander--Gorenstein exact dg categories. Our bijection generalizes Iyama--Solberg correspondence for module categories.
