In this paper, we study isomorphism classes of local, Artinian, Gorenstein k-algebras A whose maximal ideal M satisfies dimk(M3/M4)=1 by means of Macaulay's inverse system generalizing a recent result by Elias and Rossi. Then we use such results in order to complete the description of the singular locus of the Gorenstein locus of Hilb11(pn).

Abstract
In this paper, we study isomorphism classes of local, Artinian, Gorenstein k-algebras A whose maximal ideal M satisfies dimk(M3/M4)=1 by means of Macaulay's inverse system generalizing a recent result by Elias and Rossi. Then we use such results in order to complete the description of the singular locus of the Gorenstein locus of Hilb11(pn).File in questo prodotto:
