Stable forms and Killing spinors

speaker: Diego Conti (Dipartimento di Matematica e Applicazioni - Università di Milano Bicocca)

abstract: Consider a Riemannian spin manifold with a spinor which is either parallel or Killing. The restriction of the spinor to a hypersurface satisfies a differential equation involving the second fundamental form. In low dimensions, the geometric structure defined by the restricted spinor can be characterized in terms of stable differential forms. I shall discuss the converse construction in the five-dimensional case.
