Exterior-Model Spinors in Split Rank: Exact Levi Images and Square-Determinant Obstructions

Arthur F. Ramos, David B. Hulak, Ruy J. G. B. de Queiroz

Let $K$ be a field with $2\in K^{\times }$, and let $H_W$ denote the standard hyperbolic form on $W\oplus W^{\ast }$. We study the exterior spinor model $S=\bigwedge V(W)$ together with…
