Let Λ be a radical square zero Nakayama algebra with n simple modules and let Γ be the Auslander algebra of Λ . Then every indecomposable direct summand of a tilting Γ -module is either simple or projective. Moreover, if Λ is self-injective, then the number of tilting Γ -modules is 2 n ; otherwise, the number of tilting Γ -modules is 2 n − 1 .

对零平方根中山代数的 Auslander 代数上的倾斜模进行分类
让Λ 是一个激进的零平方 Nakayama 代数n 简单的模块,让Γ 是的 Auslander 代数Λ . 然后每一个不可分解的直接累加一个倾斜Γ -module 是简单的或投射的。此外,如果Λ 是自射的,那么倾斜的次数Γ -模块是2 n ; 否则,倾斜的次数Γ -模块是2 n - 1 .
