Resumen:
Superstring/M-theory compactified on compact Ricci flat manifolds have recently been con-jectured to exhibit instabilities whenever the metrics do not have special holonomy. We useworld-sheet conformal field theory to investigate instabilities of Type II superstring theories oncompact, Ricci flat, spin 3-manifolds including a world-sheet description of their spin structures.The instabilities are signalled by the appearance of stringy tachyons at small radius and a neg-ative (1-loop) vacuum energy density at large radius. We briefly discuss the extension to higherdimensions.
