Toward Permutation Bases in the Equivariant Cohomology Rings of Regular Semisimple Hessenberg Varieties [PDF]
La Matematica, 2022 Recent work of Shareshian and Wachs, Brosnan and Chow, and Guay-Paquet connects the well-known Stanley–Stembridge conjecture in combinatorics to the dot action of the symmetric group Sn\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage ...

Geometric Batyrev–Manin–Peyre for equivariant compactifications of additive groups [PDF]
Beiträge zur Algebra und Geometrie / Contributions to Algebra and Geometry, 2021 Building on previous works by Bilu, Chambert-Loir and Loeser, we study the asymptotic behaviour of the moduli space of sections of a given family over a smooth projective curve, assuming that the generic fiber is an equivariant compactification of a ...

Lannes’s T–functor and equivariant Chow rings [PDF]
Algebraic and Geometric Topology, 2019 For $X$ a smooth scheme acted on by a linear algebraic group $G$ and $p$ a prime, the equivariant Chow ring $CH^*_G(X)/p$ is an unstable algebra over the Steenrod algebra. We compute Lannes's $T$-functor applied to $CH^*_G(X)/p$.

Riemann-Roch for equivariant Chow groups [PDF]
, 1999 The purpose of this paper is to prove an equivariant Riemann-Roch theorem for schemes or algebraic spaces with an action of a linear algebraic group $G$.

Equivariant operational Chow rings of $T$-linear schemes [PDF]
Documenta Mathematica, 2013 We study T-linear schemes, a class of objects that in- cludes spherical and Schubert varieties. We provide a localization theorem for the equivariant Chow cohomology of these schemes that does not depend on resolution of singularities.

Equivariant noncommutative motives [PDF]
, 2015 Given a finite group G, we develop a theory of G-equivariant noncommutative motives. This theory provides a well-adapted framework for the study of G-schemes, Picard groups of schemes, G-algebras, 2-cocycles, equivariant algebraic K-theory, orbifold ...

PARABOLIC KAZHDAN–LUSZTIG BASIS, SCHUBERT CLASSES, AND EQUIVARIANT ORIENTED COHOMOLOGY [PDF]
Journal of the Institute of Mathematics of Jussieu, 2016 We study the equivariant oriented cohomology ring $\mathtt{h}_{T}(G/P)$ of partial flag varieties using the moment map approach. We define the right Hecke action on this cohomology ring, and then prove that the respective Bott–Samelson classes in ...

Rost motives, affine varieties, and classifying spaces [PDF]
Journal of the London Mathematical Society, 2015 In this article we investigate ordinary and equivariant Rost motives. We provide an equivariant motivic decomposition of the variety of full flags of a split semisimple algebraic group G over a field, a motivic decomposition of E/B for a G ‐torsor E over

On the Boundary and Intersection Motives of Genus 2 Hilbert-Siegel Varieties [PDF]
Documenta Mathematica, 2018 We study genus 2 Hilbert-Siegel varieties, i.e. Shimura varieties $S_K$ corresponding to the group $\mbox{GSp}_{4,F}$ over a totally real field $F$, along with the relative Chow motives $^\lambda \mathcal{V}$ of abelian type over $S_K$ obtained from ...

Cdh descent in equivariant homotopy K-theory [PDF]
, 2016 We construct geometric models for classifying spaces of linear algebraic groups in G-equivariant motivic homotopy theory, where G is a tame group scheme.
