Abstract

We study ideals in a local ring R whose quotient rings induce large homomorphisms of local rings. We characterize such ideals in terms of the maps of Koszul homologies over several classes of local rings, including complete intersections, Koszul rings, and some classes of Golod rings.

检测局部环大同态的一些标准

摘要

我们研究局部环R 中的理想,其商环引起局部环的大同态。我们根据几类局部环上的 Koszul 同源图来描述这些理想,包括完全交集、Koszul 环和一些类别的 Golod 环。
