- W2013092613 abstract "In this paper, we will use techniques of noncommutative projective geometry to construct examples of algebras R over a field k not satisfying the following two types of symmetric behaviors of Ext-groups: ( EE ) For any pair of finitely generated R -modules ( M , N ) , dim k Ext R i ( M , N ) < ∞ for all i ∈ N if and only if dim k Ext R i ( N , M ) < ∞ for all i ∈ N . ( ee ) For any pair of finitely generated R -modules ( M , N ) , Ext R i ( M , N ) = 0 for all i ≫ 0 if and only if Ext R i ( N , M ) = 0 for all i ≫ 0 . In particular, and contrary to the commutative case, we give a simple example of a noncommutative noetherian Gorenstein (Frobenius) local algebra satisfying ( uac ) (uniform Auslander condition) but not satisfying ( ee )." @default.
