Singularity Categories of Higher Nakayama Algebras
Abstract
For a higher Nakayama algebra in the sense of Jasso-K\"{u}lshammer, we show that the singularity category of is triangulated equivalent to the stable module category of a self-injective higher Nakayama algebra. This generalizes a similar result for usual Nakayama algebras due to Shen. Our proof relies on the existence of -cluster tilting subcategories in the module category of and the result of Kvamme that each -cluster tilting subcategory of induces a -cluster tilting subcategory in its singularity category. Moreover, our result provides many concrete examples of the triangulated Auslander-Iyama correspondence introduced by Jasso-Muro, namely, there is a bijective correspondence between the equivalence classes of the singularity categories of -Nakayama algebras with its basic -cluster tilting object and the isomorphism classes of self-injective -Nakayama algebras.
