Ramanujan Complexes from Unitary Groups over Number Fields
Rahul Dalal, Alberto Mínguez, Jiandi Zou
In this article, we construct new families of Ramanujan complexes with local structure distinct from all previously known examples. Our approach is based on unitary groups over num…

Thomas Lanard, Alberto Mínguez
Let be a locally compact non-Archimedean field of characteristic , and let be either the split special orthogonal group or the symplectic group $…
Local Intertwining Relations and Co-tempered -packets of Classical Groups
Hiraku Atobe, Wee Teck Gan, Atsushi Ichino +3
The local intertwining relation is an identity that gives precise information about the action of normalized intertwining operators on parabolically induced representations. We pro…
