Vanishing of Hochschild Cohomologies for Local Rings with Embedding Dimension Two
Published online by Cambridge University Press: 20 November 2018
Abstract
Let S = k[[x,y]] be a formal power series ring in two variables x, y over a field k and I an (x, y)-primary ideal of S. We show that S/I is selfinjective if Hi(S/I, S/I ⊗k S/I) = 0 for i = 1 and 2.
