Clifford Multiplication on Spinor Abelian Varieties

Algebraic Geometry 2025-10-24 v2

Abstract

We define a spinor Abelian variety SΔS_{\Delta} to be a complex Abelian variety whose tangent space at the origin is a space of spinors for a suitable complex Clifford algebra Cq(V)\mathbb{C}_{q}(V). We examine intrinsic properties of such varieties and the connection between Clifford multiplication and their endomorphism algebras. We then extend the analysis of Clifford multiplication to the dual torus Pic0(SΔ)Pic^{0}(S_{\Delta}).
