Pseudo-Reimannian metrics with parallel spinor fields and vanishing Ricci tensor

open access: yes, 2000
I discuss geometry and normal forms for pseudo-Riemannian metrics with parallel spinor fields in some interesting dimensions. I also discuss the interaction of these conditions for parallel spinor fields with the condition that the Ricci tensor vanish ...
