On higher Hessians and the Lefschetz properties
Abstract
We deal with a generalization of a Theorem of P. Gordan and M. Noether on hypersurfaces with vanishing (first) Hessian. We prove that for any given , and there are infinitely many irreducible hypersurfaces , of degree , not cones and such that their Hessian determinant of order , , vanishes identically. The vanishing of higher Hessians is closely related with the Strong (or Weak) Lefschetz property for standard graded Artinian Gorenstein algebra, as pointed out firstly in \cite{Wa1} and later in \cite{MW}. As an application we construct for each pair infinitely many standard graded Artinian Gorenstein algebras , of codimension and with socle degree which do not satisfy the Strong Lefschetz property, failing at an arbitrary step with . We also prove that for each pair , and except , , and there are infinitely many standard graded Artinian Gorenstein algebras of codimension , with socle degree , with unimodal Hilbert vectors which do not satisfy the Weak Lefschetz property.
