Incidence stratifications on Hilbert schemes of smooth surfaces, and an application to Poisson structures

, 2015
Given a smooth curve on a smooth surface, the Hilbert scheme of the surface is stratified according to the length of the intersection with the curve. The strata are highly singular. We show that this stratification admits a natural log-resolution, namely

Evaluation of filaggrin 2 expression in dogs with atopic dermatitis before and after oclacitinib maleate administration

Veterinary Dermatology, Volume 36, Issue 4, Page 453-461, August 2025.
Background – Canine atopic dermatitis (cAD) is a chronic, inflammatory, multifactorial and pruritic disease. The presence of skin barrier impairment (e.g. filaggrin alterations), along with abnormal immune responses, can negatively impact cutaneous barrier function.

A Smooth Four-Dimensional G-Hilbert Scheme [PDF]

, 2004
2000 Mathematics Subject Classification: 14C05, 14L30, 14E15, 14J35.When the cyclic group G of order 15 acts with some specific weights on affine four-dimensional space, the G-Hilbert scheme is a crepant resolution of the quotient A^4 / G.

A Dual of the Chow Transformation

Complex Manifolds, 2018
We define a dual of the Chow transformation of currents on the complex projective space. This transformation factorizes a left inverse of the Chow transformation and its composition with the Chow transformation is a right inverse of a linear diferential ...

The structure of the inverse system of Gorenstein k-algebras

, 2017
Macaulay's Inverse System gives an effective method to construct Artinian Gorenstein k-algebras. To date a general structure for Gorenstein k-algebras of any dimension (and codimension) is not understood. In this paper we extend Macaulay's correspondence

A Compactification of Open Varieties

, 2002
In this paper we show a general method to compactify certain open varieties by adding normal crossing divisors. This is done by proving that {\it blowing up along an arrangement of subvarieties} can be carried out.

Arithmetically Cohen--Macaulay curves in P^4 of degree 4 and genus 0

, 1996
We show that the arithmetically Cohen--Macaulay (ACM) curves of degree 4 and genus 0 in ${\bold P}^4$ form an irreducible subset of the Hilbert scheme. Using this, we show that the singular locus of the corresponding component of the Hilbert scheme has ...

Flags of sheaves, quivers and symmetric polynomials

Forum of Mathematics, Sigma
We study a quiver description of the nested Hilbert scheme of points on the affine plane and its higher rank generalization – that is, the moduli space of flags of framed torsion-free sheaves on the projective plane.
