Abstract

We investigate the compactification of D=11 supergravity to D=5,4,3, on compact manifolds of holonomy (Calabi-Yau), , and , respectively, making use of examples of the latter two cases found recently by Joyce. In each case the lower dimensional theory is a Maxwell/Einstein supergravity theory. We find evidence for an equivalence, in certain cases, with heterotic string compactifications from D=10 to D=5,4,3, on compact manifolds of holonomy (), , and , respectively. Calabi-Yau manifolds with Hodge numbers play a significant role in the proposed equivalences.
