具有线性分解的Artin Gorenstein代数

Artinian Gorenstein algebras with linear resolutions

Sabine El Khoury, Andrew R. Kustin

摘要:

固定一对正整数d和n。我们建立了一个环R和一个R-模的复G,它具有以下泛性质。设P是域上的d元多项式环,I是P中由n次齐次形式生成的d次Gorenstein理想.若P/I的自由P-模分解是线性的,则存在R到P的环同态,使得P张量G是P/I的自由P-模的极小齐次分解.我们的结构是坐标自由的。

英文摘要:

Fix a pair of positive integers d and n. We create a ring R and a complex G of R-modules with the following universal property. Let P be a polynomial ring in d variables over a field and let I be a grade d Gorenstein ideal in P which is generated by homogeneous forms of degree n. If the resolution of P/I by free P-modules is linear, then there exists a ring homomorphism from R to P such that P tensor G is a minimal homogeneous resolution of P/I by free P-modules. Our construction is coordinate free.
