Let A be the Auslander algebra of a finite-dimensional basic connected Nakayama algebra A with radical cube zero and n simple modules. Then the cardinality #tiltA of the set consisting of isomorphism classes of basic tilting A-modules is #tiltA = (1+2)2n2(12)2n2 22 , if Ais non-self-injective withn 4;[(1 + 2 )2n (1 2 )2n ]2 + 4,ifAis self-injective withn 2.

具有根立方零的中山代数的 Auslander 代数上的倾斜模

一种'是一个有限维基本连通 Nakayama 代数的 Auslander 代数一种根立方零和n简单的模块。然后基数#倾斜一种'由基本倾斜的同构类组成的集合一种'-模块是 #倾斜一种' = (1+2)2n-2-(1-2)2n-2 22 , 如果 一种是非自内射的n 4;[(1 + 2 )2n - (1 - 2 )2n ]2 + 4,如果一种是自内射的n 2.
