Unstable hyperplanes for Steiner bundles and multidimensional matrices
نویسندگان
چکیده
The above remarks set up a basic link between non degenerate multidimensional matrices of boundary format and vector bundles on a product of projective spaces. In the particular case p = 2 the (dual) vector bundle SA lives on the projective space P , n = k2, and is a Steiner bundle as defined in [DK]. We can keep to SA the name Steiner also for p ≥ 3. The action of of SL(V0)×. . .×SL(Vp) onA translates to an action on the corresponding bundle in two steps:

Invariant multidimensional matrices
In [AO] the authors study Steiner bundles via their unstable hyperplanes and proved that (see [AO], Tmm 5.9) : A rank n Steiner bundle on Pn which is SL(2,C) invariant is a Schwarzenberger bundle. In this note we give a very short proof of this result based on Clebsch-Gordon problem for SL(2,C)modules.
متن کاملSchwarzenberger Bundles of Arbitrary Rank on the Projective Space
We introduce a generalized notion of Schwarzenberger bundle on the projective space. Associated to this more general definition, we give an ad-hoc notion of jumping subspaces of a Steiner bundle on P (which in rank n coincides with the notion of unstable hyperplane introduced by Vallès, Ancona and Ottaviani). For the set of jumping hyperplanes, we find a sharp bound for its dimension. We also c...
متن کاملStabilizers for Nondegenerate Matrices of Boundary Format and Steiner Bundles
In this paper nondegenerate multidimensional matrices of boundary format in V0 ⊗ · · · ⊗ Vp are investigated by their link with Steiner vector bundles on product of projective spaces. For any nondegenerate matrix A the stabilizer for the SL(V0)×· · ·×SL(Vp)action, Stab(A), is completely described. In particular we prove that there exists an explicit action of SL(2) on V0 ⊗ · · · ⊗ Vp such that ...
متن کاملLogarithmic bundles of deformed Weyl arrangements of type A_2
We consider deformations of the Weyl arrangement of type A2, which include the extended Shi and Catalan arrangements. These last ones are well-known to be free. We study their sheaves of logarithmic vector fields in all other cases, and show that they are Steiner bundles. Also, we determine explicitly their unstable lines. As a corollary, some counter-examples to the shift isomorphism problem a...
متن کاملNondegenerate Multidimensional Matrices and Instanton Bundles
In this paper we prove that the moduli space of rank 2n symplectic instanton bundles on P2n+1, defined from the well-known monad condition, is affine. This result was not known even in the case n = 1, where by Atiyah, Drinfeld, Hitchin, and Manin in 1978 the real instanton bundles correspond to self-dual Yang Mills Sp(1)-connections over the 4-dimensional sphere. The result is proved as a conse...
