备注：: 10 pages

英文摘要：

Let $G_k$ be a split algebraic group over $k$. Given a non-trivial $G_k$-torsor $G$, we consider the (twisted) flag variety $F=G/B_k$ for the Borel subgroup $B_k$ containing in $G_k$. The purpose of this paper is the study how to compute the Chow rings $CH^*(F)$ for various $F$ over some extension fields $K$ of $k$.

Computations of the Comodule Structures of the Chow rings of Flag Varieties

Let $G$ be a connected reductive group, and $G/B$ be its flag variety. Let $π:G\to G/B$ be the natural projection. In this paper, we developed an algorithm to describe the map $π^* :\operatorname{CH}^*(G/B;\mathbb{F}_p)\longrightarrow \operatorname{CH}^*(G;\mathbb{F}_p)$ in terms of Schubert cells. Taking advantage of the Pieri rule, we give an explicit formula for $A$-type, $C$-type, $G_2$, $F_4$ of the cohomology map $π^* :\operatorname{CH}^*(G/B;\mathbb{F}_p)\longrightarrow \operatorname{CH}^*(G;\mathbb{F}_p)$, and some partial result of $π^*$ is given for $E_6$ and $E_7$. Denote the group …

Algebraic cobordism and flag varieties

Let $X$ be an algebraic variety over $k$ such that $\bar X=X\otimes_k\bar k$ is cellular. We study torsion elements in the Chow ring $CH^*(X)$ which corresponds to $v_iy$ in the algebraic cobordism $Ω^*(\bar X)$ where $0\not=y\in CH^*(\bar X)/p$ and $v_i$ is the generator of $BP^*$ with $|v_i|=-2(p^i-1).$ In particular, we try to compute $CH^*(X)$ from $Ω^*(\bar X)$ when $X$ are twisted complete flag varieties.

Oriented Schubert calculus in Chow-Witt rings of Grassmannians

We apply the previous calculations of Chow-Witt rings of Grassmannians to develop an oriented analogue of the classical Schubert calculus. As a result, we get complete diagrammatic descriptions of the ring structure in Chow-Witt rings and twisted Witt groups. In the resulting arithmetic refinements of Schubert calculus, the multiplicity of a solution subspace is a quadratic form encoding additional orientation information. We also discuss a couple of applications, such as a Chow-Witt version of the signed count of balanced subspaces of Fehér and Matszangosz.

基于非交换基模的环面和扭曲投射齐次簇的加法不变量

Additive invariants of toric and twisted projective homogeneous varieties via noncommutative motives

I. Panin在90年代证明了扭曲投射齐次簇的代数K理论可以用中心单代数代数来表示。后来，Merkurjev和Panin将复曲面簇的代数K理论描述为可分代数的代数K理论的直接和项。本文利用最近的非对易动机理论，将Panin和Merkurjev-Panin计算从代数K理论推广到所有的加法不变量.作为第一个应用，我们充分计算的循环同调（及其所有的变种）扭曲的投射齐次品种。作为第二个应用，我们证明了一个扭曲的投射齐次簇的非交换动机是平凡的当且仅当相关的中心单代数的Brauer类是平凡的。在此过程中，我们构造了一个完全忠实的张量函子，从Merkurjev-Panin的motivic范畴到Kontsevich的非交换Chow motives范畴，这是独立的兴趣。
