Homological branching law for : projectivity and indecomposability

KY Chan - Inventiones mathematicae, 2021 - Springer
Let F be a non-Archimedean local field. This paper studies homological properties of
irreducible smooth representations restricted from GL _ n+ 1 (F) GL n+ 1 (F) to GL _n (F) GL …

Twisted GGP problems and conjectures

WT Gan, BH Gross, D Prasad - Compositio Mathematica, 2023 - cambridge.org
In a series of three earlier papers, we considered a family of restriction problems for classical
groups (over local and global fields) and proposed precise answers to these problems using …

On the Product Functor on Inner forms of the General Linear Group Over A Non-Archimedean Local Field

KY Chan - Transformation Groups, 2024 - Springer
Abstract Let\(G_n\) be an inner form of a general linear group over a non-Archimedean local
field. We fix an arbitrary irreducible representation\(\sigma\) of\(G_n\). Building on the work of …

Fourier-Jacobi models of Deligne-Lusztig characters and depth zero local descent for unitary groups

D Liu, JJ Ma, F Shi - arXiv preprint arXiv:2208.02308, 2022 - arxiv.org
In this paper, we deduce explicit multiplicity formulas of the Fourier-Jacobi model for Deligne-
Lusztig characters of finite symplectic groups, unitary groups, and general linear groups. We …

Homological aspects of branching laws

D Prasad - arXiv preprint arXiv:2302.03492, 2023 - arxiv.org
In this mostly expository article, we consider certain homological aspects of branching laws
for representations of a group restricted to its subgroups in the context of $ p $-adic groups …
