Frobenius splitting of Schubert varieties of semi-infinite flag manifolds

open access: yesForum of Mathematics, Pi, 2021
We exhibit basic algebro-geometric results on the formal model of semi-infinite flag varieties and its Schubert varieties over an algebraically closed field ${\mathbb K}$ of characteristic $\neq 2$ from scratch.

Inverse K-Chevalley formulas for semi-infinite flag manifolds, I: minuscule weights in ADE type

open access: yesForum of Mathematics, Sigma, 2021
We prove an explicit inverse Chevalley formula in the equivariant K-theory of semi-infinite flag manifolds of simply laced type. By an ‘inverse Chevalley formula’ we mean a formula for the product of an equivariant scalar with a Schubert class, expressed

Pseudomonas aeruginosa isolation from dog grooming products used by private owners or by professional pet grooming salons: prevalence and risk factors

open access: yesVeterinary Dermatology, Volume 33, Issue 4, Page 316-e73, August 2022., 2022
Abstract Background Pseudomonas aeruginosa is the most commonly isolated bacterium from skin lesions of dogs with post‐grooming furunculosis (PGF). It is frequently found in human hair and skin care products, and may pose a health risk to consumers. Information regarding the prevalence of P. aeruginosa contamination of dog grooming products is lacking.

Reproducibility of serum testing for environmental allergen‐specific IgE in dogs in Europe

open access: yesVeterinary Dermatology, Volume 32, Issue 3, Page 251-e67, June 2021., 2021
Background – Serum testing for allergen‐specific immunoglobulin (Ig)E is commonly employed to identify allergens used for allergen‐specific immunotherapy in dogs, yet the reliability of results has been a matter of debate. Objective – The aim of this study was to evaluate the reproducibility of serum tests for environmental allergen‐specific IgE in ...

Geometry of intersections of some secant varieties to algebraic curves

open access: yesJournal of the London Mathematical Society, Volume 103, Issue 1, Page 288-313, January 2021., 2021
Abstract For a smooth projective curve, the cycles of subordinate or, more generally, secant divisors to a given linear series are among some of the most studied objects in classical enumerative geometry. We consider the intersection of two such cycles corresponding to secant divisors of two different linear series on the same curve and investigate the

On First Order Congruences of Lines in P 4 with Generically Non-reduced Fundamental Surface [PDF]

open access: yes, 2004
. In this article we obtain a complete description of the congruences of lines in P 4 oforder one provided that the fundamental surface F is non-reduced (and possibly reducible) at oneof its generic points, and their classification under the hypothesis ...

Serum concentrations of IL‐31 in dogs with nonpruritic mast cell tumours or lymphoma

open access: yesVeterinary Dermatology, Volume 31, Issue 6, Page 466-e124, December 2020., 2020
Background The aim of this study was to compare serum interleukin (IL)‐31 concentrations in dogs with lymphoma and mast cell tumours (MCT) without pruritus to those of healthy dogs. Hypothesis/Objectives To determine if IL‐31 plays a role in tumour pathogenesis and if IL‐31 could be a biological marker for disease progression.

Decomposition of homogeneous polynomials with low rank [PDF]

open access: yes, 2010
Let $F$ be a homogeneous polynomial of degree $d$ in $m+1$ variables defined over an algebraically closed field of characteristic zero and suppose that $F$ belongs to the $s$-th secant varieties of the standard Veronese variety $X_{m,d}\subset \mathbb{P}^

Apolarity, Hessian and Macaulay polynomials [PDF]

open access: yes, 2012
A result by Macaulay states that an Artinian graded Gorenstein ring R of socle dimension one and socle degree b can be realized as the apolar ring of a homogeneous polynomial f of degree b.

Gromov-Witten invariants on Grassmannians [PDF]

open access: yes, 2003
We prove that any three-point genus zero Gromov-Witten invariant on a type A Grassmannian is equal to a classical intersection number on a two-step flag variety. We also give symplectic and orthogonal analogues of this result; in these cases the two-step
