The $\mathrm{SL}_1(D)$-distinction problem

Hengfei Lu

Vol. 300 (2019), No. 1, 65–82
Abstract

We use the local theta correspondences between the quaternionic Hermitian groups and the quaternionic skew-Hermitian groups to understand the distinction problem for the symmetric pair SL2(E)SL1(D), where E is a quadratic field extension of a nonarchimedean local field F and D is a 4-dimensional division quaternion algebra over F.
