Ext-multiplicity theorem for standard representations of

KY Chan - Mathematische Zeitschrift, 2023 - Springer
Let π 1 be a standard representation of GL n+ 1 (F) and let π 2 be the smooth dual of a
standard representation of GL n (F). When F is non-Archimedean, we prove that Ext GL n (F) …

We state a conjecture that relates the derived category of smooth representations of a by
showing that the functor should be given by the derived tensor product with the family of …

Restriction for general linear groups: the local non-tempered Gan–Gross–Prasad conjecture (non-Archimedean case)

KY Chan - Journal für die reine und angewandte Mathematik …, 2022 - degruyter.com

Beijing notes on the categorical local Langlands conjecture

D Hansen - arXiv preprint arXiv:2310.04533, 2023 - arxiv.org
We formulate some refinements and complements to the categorical local Langlands
conjecture of Fargues-Scholze. In particular, we state the expected compatibilities with …

The Gelfand–Graev representation of classical groups in terms of Hecke algebras

P Bakić, G Savin - Canadian Journal of Mathematics, 2023 - cambridge.org
Let G be a p-adic classical group. The representations in a given Bernstein component can
be viewed as modules for the corresponding Hecke algebra—the endomorphism algebra of …

Local Langlands in families: The banal case

We state a conjecture, local Langlands in families, connecting the centre of the category of
smooth representations on $\mathbb {Z}[\sqrt {q}^{-1}] $-modules of a quasi-split $ p $-adic …

Construction of simple quotients of Bernstein-Zelevinsky derivatives and highest derivative multisegments

KY Chan - arXiv preprint arXiv:2111.13286, 2021 - arxiv.org
Let $ F $ be a non-Archimedean field. A sequence of derivatives of generalized Steinberg
representations can be used to construct simple quotients of Bernstein-Zelevinsky …

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 …
