Hilbert Series of Certain Jet Schemes of Determinantal Varieties
We consider the affine variety Z 2,2 of first order jets over Z m,n 2 , where Z 2 is the classical determinantal variety given by the vanishing of all 2×2 minors of a generic m×n matrix. When 2 < m ≤ n, this jet scheme Z 2,2 has two irreducible components: a trivial component, isomorphic to an affine space, and a nontrivial component that is the closure of the jets supported over the smooth loc...
متن کاملHilbert functions of ladder determinantal varieties
We consider algebraic varieties de)ned by the vanishing of all minors of a )xed size of a rectangular matrix with indeterminate entries such that the indeterminates in these minors are restricted to lie in a ladder shaped region of the rectangular array. Explicit formulae for the Hilbert function of such varieties are obtained in (i) the rectangular case by Abhyankar (Rend. Sem. Mat. Univers. P...
متن کاملToric Varieties in Hilbert Schemes
Given a field K, let R be the power series ring K[[x1, . . . , xn]]. There is a natural action of Aut(R) on the Hilbert scheme Hilb(R) parameterizing ideals in R of colength d. Recall from [10] that given a smooth variety X of dimension n and a monomial ideal I ⊂ R of finite colength, the space U(I) parametrizing subschemes of X isomorphic to Spec(R/I) sits naturally inside a suitable Hilbert s...
متن کاملQuiver Varieties and Hilbert Schemes
In this note we give an explicit geometric description of some of the Nakajima’s quiver varieties. More precisely, if X = C, Γ ⊂ SL(C) is a finite subgroup, and XΓ is a minimal resolution of X/Γ, we show that X (the Γ-equivariant Hilbert scheme of X), and X [n] Γ (the Hilbert scheme of XΓ) are quiver varieties for the affine Dynkin graph corresponding to Γ via the McKay correspondence with the ...
متن کاملHilbert Polynomial of a Certain Ladder-Determinantal Ideal
A ladder-shaped array is a subset of a rectangular array which looks like a Ferrers diagram corresponding to a partition of a positive integer. The ideals generated by the p-by-p minors of a ladder-type array of indeterminates in the corresponding polynomial ring have been shown to be hilbertian (i.e., their Hilbert functions coincide with Hilbert polynomials for all nonnegative integers) by Ab...
