Weighted projective lines and Hochschild cohomology

Felix Schremmer

We describe the dimensions of Hochschild (co)homology groups of weighted projective curves over complex numbers. Surprisingly, all but one of those numbers depend only on the genus…

Affine Deligne-Lusztig varieties beyond the minute case

Felix Schremmer, Eva Viehmann

Affine Deligne-Lusztig varieties in the fully Hodge-Newton decomposable (or minute) case are the only larger class of ADLVs which could be described completely in the past. Instanc…

Lifting Deligne-Lusztig Reduction and Geometric Coxeter Type Elements

Sian Nie, Felix Schremmer, Qingchao Yu

Cases of Shimura varieties where the special fibre of a Rapoport-Zink space is simply the union of classical Deligne-Lusztig varieties are known as fully Hodge-Newton decomposable…

Affine Deligne-Lusztig Varieties of Positive Coxeter Type

Felix Schremmer, Ryosuke Shimada, Qingchao Yu

We introduce a class of affine Deligne--Lusztig varieties that we call of positive Coxeter type. We show that the affine Deligne--Lusztig varieties of positive Coxeter type have a…

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…

Affine Deligne-Lusztig varieties via the double Bruhat graph I: Semi-infinite orbits

Felix Schremmer

We introduce a new language to describe the geometry of affine Deligne-Lusztig varieties in affine flag varieties. This first part of a two paper series develops the definition and…

Newton Strata in Levi Subgroups

Felix Schremmer

Certain Iwahori double cosets in the loop group of a reductive group, known under the names of -alcoves or -alcoves, play an important role in the study of affine Delig…
