Artin-Schelter正则代数与范畴

Artin-Schelter regular algebras and categories

Roberto Martinez-Villa, Øyvind Solberg

摘要:

出于建设有限维代数的表示论,我们推广的概念,Artin-Schelter正则代数的尺寸$n$代数和类别,包括Auslander代数和分级模拟无限表示类型。证明了广义Artin-Schelter正则代数或维数为$n$的一类代数与经典Artin-Schelter正则代数具有共同的性质.特别地,当它们具有对偶性时,它们满足Serre对偶公式,并且最大投射维数的简单对象的好集的$\Ext$ -范畴$n$是有限长的Frobenius范畴.

英文摘要:

Motivated by constructions in the representation theory of finite dimensional algebras we generalize the notion of Artin-Schelter regular algebras of dimension $n$ to algebras and categories to include Auslander algebras and a graded analogue for infinite representation type. A generalized Artin-Schelter regular algebra or a category of dimension $n$ is shown to have common properties with the classical Artin-Schelter regular algebras. In particular, when they admit a duality, then they satisfy Serre duality formulas and the $\Ext$-category of nice sets of simple objects of maximal projective dimension $n$ is a finite length Frobenius category.
