A counterexample to a conjecture of Ding
arXiv:1506.09168
Abstract
We give a counterexample to a conjecture posed by S. Ding regarding the index of a Gorenstein local ring by exhibiting several examples of one dimensional local complete intersections of embedding dimension three with index 5 and generalized Löewy length 6.
