Auslander代数与偏序集的扭双指标代数

Auslander algebras and twisted double incidence algebras

  • 摘要: 证明了代数 A的 Auslander代数是扭双指标代数当且仅当 A是局部代数 K x/( xn)

     

    Abstract: It is proved that the Auslander algebra of an algebra A is a twisted double incidence algebra of some poset X if and only if A is the local algebra Kx/(x) n if and only if X is linearly ordered.
