Special periods and some non-tempered cases of the Gan-Gross-Prasad conjecture

Jaeho Haan, Sanghoon Kwon

In this paper, we establish a relationship between special periods and special L-values of automorphic representations of classical groups, and prove the non-tempered global Gan--G…

The local converse theorem for quasi-split $O_{2 n}$ and $S O_{2 n}$

Jaeho Haan, Yeansu Kim, Sanghoon Kwon

Let $F$ be a non-archimedean local field of characteristic not equal to 2. In this paper, we prove the local converse theorem for quasi-split $A ~ _{2 n} (F)$ and $\SO_{2n}(F)$, via th…
