Type IIA-heterotic duals with maximal supersymmetry Original Research Article

Using finite abelian automorphism groups of K3 we construct orbifold candidates for Type IIAheterotic dual pairs with maximal supersymmetry in six and lower dimensions. On the heterotic side, these results extend the series of known reduced rank theories with maximal supersymmetry. The corresponding Type 11A theories generalize the Schwarz and Sen proposal for the dual of the simplest of the reduced rank theories constructed as a novel Type IIA Z2 orbifold.
