Lefschetz Elements of Artinian Gorenstein Algebras and Hessians of Homogeneous Polynomials

چکیده
We give a characterization of the Lefschetz elements in Artinian Gorenstein rings over a field of characteristic zero in terms of the higher Hessians. As an application, we give new examples of Artinian Gorenstein rings which do not have the strong Lefschetz property.

On the Weak Lefschetz Property for Artinian Gorenstein Algebras of Codimension Three
We study the problem of whether an arbitrary codimension three graded artinian Gorenstein algebra has the Weak Lefschetz Property. We reduce this problem to checking whether it holds for all compressed Gorenstein algebras of odd socle degree. In the first open case, namely Hilbert function (1, 3, 6, 6, 3, 1), we give a complete answer in every characteristic by translating the problem to one of...
متن کاملThe central simple modules of Artinian Gorenstein algebras
Let A be a standard graded Artinian K-algebra, with char K = 0. We prove the following. 1. A has the Weak Lefschetz Property (resp. Strong Lefschetz Property) if and only if Gr(z)(A) has the Weak Lefschetz Property (resp. Strong Lefschetz Property) for some linear form z of A. 2. If A is Gorenstein, then A has the Strong Lefschetz Property if and only if there exists a linear form z of A such t...
متن کاملReduced Arithmetically Gorenstein Schemes and Simplicial Polytopes with Maximal Betti Numbers
An SI-sequence is a finite sequence of positive integers which is symmetric, unimodal and satisfies a certain growth condition. These are known to correspond precisely to the possible Hilbert functions of Artinian Gorenstein algebras with the Weak Lefschetz Property, a property shared by most Artinian Gorenstein algebras. Starting with an arbitrary SI-sequence, we construct a reduced, arithmeti...
متن کاملThe strong Lefschetz property for Artinian algebras with non-standard grading
Let A = ⊕ i=0Ai be a graded Artinian K-algebra, where Ac 6= (0) and charK = 0. (The grading may not necessarily be standard.) Then A has the strong Lefschetz property if there exists an element g ∈ A1 such that the multiplication×g c−2i : Ai −→ Ac−i is bijective for every i = 0, 1, . . . , [c/2]. The main results obtained in this paper are as follows: 1. A has the strong Lefschetz property if a...
متن کاملThe Hilbert functions which force the Weak Lefschetz Property
The purpose of this note is to characterize the finite Hilbert functions which force all of their artinian algebras to enjoy the Weak Lefschetz Property (WLP). Curiously, they turn out to be exactly those (characterized by Wiebe in [Wi]) whose Gotzmann ideals have the WLP. This implies that, if a Gotzmann ideal has the WLP, then all algebras with the same Hilbert function (and hence lower Betti...
