Non-perturbative heterotic duals of M-theory on G 2 orbifolds
Abstract By fibering the duality between the E 8 × E 8 heterotic string on T 3 and M-theory on K3, we study heterotic duals of M-theory compactified on G 2 orbifolds of the form T 7 / ℤ 2 3 $$ {\mathbb{Z}}_2^3 $$ . While the heterotic compactification space is straightforward, the description of the...
