  • In this manuscript we consider a special complex torus, denoted $S_{Δ_{2k}}$ (for each $k \in \mathbb{N},\, k \geq 1$) and called the Dirac spinor torus. It is an Abelian variety of complex dimension $2^{k}$ whose covering space is the space of Dirac spinors, $Δ_{2k}$, for the Clifford algebra $Cl(\mathbb{C}^{2k})$ associated with the vector space $\mathbb{C}^{2k}$. Fixing an isomorphism $ρ:Cl(\mathbb{C}^{2k})\rightarrow End (Δ_{2k})$, we define Clifford multiplication on $S_{Δ_{2k}}$ as the actions of those endomorphisms in the image of $ρ$ that preserve the full rank lattice. We analyze the properties of that Clifford multiplication on the 2-torsion points of the Dirac spinor torus. We identify the Clifford actions with permutation maps that represent all isomorphism classes of these actions on the group of 2-torsion points. We provide a structure theorem describing these isomorphism classes of Clifford actions in a way that is independent of the choice of representatives. We conclude by extending the scope of our analysis to the group of $n$-torsion points and analyzing the fixed points and translation constants of entry-permuting maps, a broader class of actions of which the Clifford actions on the 2-torsion points of $S_{Δ_{2k}}$ is a subset.
