Overgroups of elementary block-diagonal subgroups in the classical symplectic group over an arbitrary commutative ring
Alexander Shchegolev
In this paper we prove a sandwich classification theorem for subgroups of the classical symplectic group over an arbitrary commutative ring that contain the elementary block-di…
