Computing Gorenstein Colength
H. Ananthnarayan
Given an Artinian local ring , we define its Gorenstein colength to measure how closely we can approximate by a Gorenstein Artin local ring. In this paper, we show th…

The Gorenstein Colength of an Artinian Local Ring
H. Ananthnarayan
In this paper, we make the notion of approximating an Artinian local ring by a Gorenstein Artin local ring precise using the concept of Gorenstein colength. We also answer the ques…
