The local theta correspondence and the local Gan-Gross-Prasad conjecture for the symplectic-metaplectic case

Abstract

We prove the local Gan-Gross-Prasad conjecture for the symplectic-metaplectic case under some assumptions. This is the last case of the local Gan-Gross-Prasad conjectures. We also prove two of Prasad's conjectures on the local theta correspondence in the almost equal rank case.
