Uniqueness of Bessel models for $\mathrm{GSpin}$ groups

Abstract

We prove the uniqueness of general Bessel models for GSpin\mathrm{GSpin} groups over a local field of characteristic zero. The proof is to reduce it to the spherical case, which has been proved by Emory and Takeda in the non-archimedean case and by Emory, Kim, and Maiti in the archimedean case.
