Branching laws for classical groups: the non-tempered case

WT Gan, BH Gross, D Prasad - Compositio Mathematica, 2020 - cambridge.org
This paper generalizes the Gan–Gross–Prasad (GGP) conjectures that were earlier
formulated for tempered or more generally generic L-packets to Arthur packets, especially …

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

Tropical geometry, quantum affine algebras, and scattering amplitudes

N Early, JR Li - arXiv preprint arXiv:2303.05618, 2023 - arxiv.org
The goal of this paper is to make a connection between tropical geometry, representations of
quantum affine algebras, and scattering amplitudes in physics. The connection allows us to …

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
We prove a local Gan–Gross–Prasad conjecture on predicting the branching law for the non-
tempered representations of general linear groups in the case of non-Archimedean fields …

Simple modules for quiver Hecke algebras and the Robinson–Schensted–Knuth correspondence

M Gurevich - Journal of the London Mathematical Society, 2023 - Wiley Online Library
We formalize some known categorical equivalences to give a rigorous treatment of smooth
representations of pp‐adic general linear groups, as ungraded modules over quiver Hecke …
