Abstract: (MSP)
This paper proves the stability, with respect to the evolution determined by thevacuum Einstein equations, of the Cartesian product of higher-dimensional Minkowskispace with a compact, Ricci-flat Riemannian manifold that admits a spinstructure and a nonzero parallel spinor. Such a product includes the example ofCalabi–Yau and other special holonomy compactifications, which play a central rolein supergravity and string theory. The stability result proved in this papershows that Penrose’s instability argument [2003] does not apply to localisedperturbations.
