$nd\mathbb{Z}$-cluster tilting subcategories of $d$-Nakayama algebras
Abstract
Jasso-K\"{u}lshammer introduced the class of -Nakayama algebras as a higher dimensional analogue of Nakayama algebras. In particular, they are endowed with a distinguished -cluster tilting subcategory. In this paper, we investigate which -Nakayama algebras admit an -cluster tilting subcategory for . The radical square zero case is already covered by results on classical Nakayama algebras due to Herschend-Kvamme-Vaso. For each remaining non-self-injective -Nakayama algebra, we provide a complete classification of its -cluster tilting subcategories. In fact, there exists at most one for a suitable integer . A self-injective -Nakayama algebra is determined by two positive integers and . We show that an -cluster tilting subcategory is only possible if and . In case , we show that such subcategory does indeed exist by constructing an explicit example.
