%0 Journal Article %T Spinorially twisted Spin structures, II: pure spinors and holonomy %A Rafael Herrera %A Noemi Santana %J Mathematics %D 2015 %I arXiv %X We introduce a notion of pure spinor for spinorially twisted spin representations, analyze the geometrical consequences of their existence, and characterize special Riemannian holonomies by the existence of parallel (twisted) pure spinor fields. %U http://arxiv.org/abs/1506.07681v1
