As an application we obtain Ikeda's criteria for the Gorensteinness of R(I) and a result of IierzogSimis-Vasconcelos characterizing when the canonical module of R(I) has the expected form.10 p.application/pdfeng(c) Universitat Autònoma de Barcelona, 1992Anells commutatiusGeometria algebraicaCommutative ringsAlgebraic geometryOn the structure of the canonical module of the Rees algebra and the associated graded ring of and idealinfo:eu-repo/semantics/article0839872019-04-26info:eu-repo/semantics/openAccess
