Jacobian Ideals of Trilinear Forms: an Application of 1-genericity

چکیده
be a trilinear form in R, and let JA denote the ideal of R generated by all the partial derivatives of A. A question that arises from the theory of hyperdeterminants (see [GKZ, page 445]) is the following: What can be said about the ideal JA? A reason for this question emerges, among other things, from results which show that information on the depth of JA and, more finely, on the primary decomposition of JA, is linked to information on the hyperdeterminant of A, (see [BW]). The difficulty with hyperdeterminants, whose definition makes sense only when n ≤ m + p − 1, is that there is no explicit formula for them. However,

On the Ideal of Minors of Matrices of Linear Forms
The ideals generated by the minors of matrices whose entries are linear forms are not yet well-understood, unless the forms themselves satisfy some strong condition. One has a wealth of information if the matrix is generic, symmetric generic or Hankel; here we tackle 1-generic matrices. We recall the definition of 1-genericity introduced in [E2] by Eisenbud: Let F be a field and X1, . . . , Xs ...
متن کاملMore General Forms of $(alpha, beta )$-fuzzy Ideals of Ordered Semigroups
This paper consider the general forms of $(alpha,beta)$-fuzzyleft ideals (right ideals, bi-ideals, interior ideals) of an orderedsemigroup, where$alpha,betain{in_{gamma},q_{delta},in_{gamma}wedgeq_{delta}, in_{gamma}vee q_{delta}}$ and $alphaneqin_{gamma}wedge q_{delta}$. Special attention is paid to$(in_{gamma},ivq)$-left ideals (right ideals, bi-ideals, interiorideals) and some related pr...
متن کاملQuasi-stability versus Genericity
Quasi-stable ideals appear as leading ideals in the theory of Pommaret bases. We show that quasi-stable leading ideals share many of the properties of the generic initial ideal. In contrast to genericity, quasistability is a characteristic independent property that can be effectively verified. We also relate Pommaret bases to some invariants associated with local cohomology, exhibit the existen...
متن کاملSingularities Appearing on Generic Fibers of Morphisms between Smooth Schemes
I give various criteria for singularities to appear on geometric generic fibers of morphism between smooth schemes in positive characteristics. This involves local fundamental groups, jacobian ideals, projective dimension, tangent and cotangent sheaves, and the effect of Frobenius. As an application, I determine which rational double points do appear on geometric generic fibers.
