Zero-dimensional affine Deligne--Lusztig varieties
Xuhua He, Sian Nie, Qingchao Yu
In this paper, we study the affine Deligne--Lusztig variety and classify all quadruples with . This question was first asked by…
Machine learning assisted exploration for affine Deligne-Lusztig varieties
Bin Dong, Xuhua He, Pengfei Jin +2
This paper presents a novel, interdisciplinary study that leverages a Machine Learning (ML) assisted framework to explore the geometry of affine Deligne-Lusztig varieties (ADLV). T…
On affine Lusztig varieties
Xuhua He
Affine Lusztig varieties encode the orbital integrals of Iwahori--Hecke functions and serve as building blocks for the (conjectural) theory of affine character sheaves. We establis…
A generalization of cyclic shift classes
Xuhua He
Motivated by Lusztig's -stable pieces, we consider the combinatorial pieces: the pairs for elements in the Weyl group and subsets of simple reflections that are…
Total positivity in twisted product of flag varieties
Huanchen Bao, Xuhua He
We show that the totally nonnegative part of the twisted product of flag varieties of a Kac-Moody group admits a cellular decomposition, and the closure of each cell is a topologic…
Affine Deligne--Lusztig varieties with finite Coxeter parts
Xuhua He, Sian Nie, Qingchao Yu
In this paper, we study affine Deligne--Lusztig varieties when the finite part of the element in the Iwahori--Weyl group is a partial -Coxeter element. We show that…
