The scalar product formula for parahoric Deligne--Lusztig induction
Charlotte Chan
Parahoric Deligne--Lusztig induction gives rise to positive-depth representations of parahoric subgroups of -adic groups. The most fundamental basic question about parahoric Del…
Affine Semigroup Algebras And Their Fibered Sums
C-Y. Jean Chan, I-Chiau Huang, Jung-Chen Liu
We study affine semigroup rings as algebras over subsemigroup rings. From this relative viewpoint with respect to a given subsemigroup ring, the fibered sum of two affine semigroup…
Generic character sheaves on parahoric subgroups
Roman Bezrukavnikov, Charlotte Chan
We study parabolic induction producing -adic sheaves on a parahoric subgroup scheme in the loop group of a reductive group. Under a genericity assumption on the input data, w…
Characterization of supercuspidal representations and very regular elements
Charlotte Chan, Masao Oi
We prove that regular supercuspidal representations of -adic groups are uniquely determined by their character values on very regular elements -- a special class of regular semi…
Geometric L-packets of Howe-unramified toral supercuspidal representations
Charlotte Chan, Masao Oi
We show that -packets of toral supercuspidal representations arising from unramified maximal tori of -adic groups are realized by Deligne--Lusztig varieties for parahoric sub…
The Drinfeld stratification for
Charlotte Chan, Alexander B. Ivanov
We define a stratification of Deligne--Lusztig varieties and their parahoric analogues which we call the Drinfeld stratification. In the setting of inner forms of GLn, we study the…
