The intersection of local Arthur packets for even orthogonal groups and applications

Alexander Hazeltine, Baiying Liu, Chi-Heng Lo

We give algorithms to explicitly compute local Arthur packets and their intersections for even orthogonal groups $G_{n}$ over $p$ -adic fields using extended multi-segments. In additi…

Algorithms on the Pyasetskii involution on local Langlands parameters of classical groups

Alexander Hazeltine, Chi-Heng Lo

We give an algorithm to compute the Pyasetskii involution for $Sp_{2 n}$ , $SO_{2 n + 1}$ and $O_{2 n}$ . The algorithm is a combination of Moeglin-Waldspurger'…

On corank 4 unitary representations of classical groups

Baiying Liu, Chi-Heng Lo, Brian Wen

In this paper, we explicitly classify the corank 4 unitary representations of symplectic or split odd special orthogonal groups over non-Archimedean local fields of characteristic…
