Title: On F-Theory/Heterotic Duality
Abstract: Using local mirror symmetry in type IIA string compactificationson Calabi--Yau $n+1$ folds $X_{n+1}$ we construct vector bundleson (possibly singular) elliptically fibered Calabi--Yau $n$-folds$Z_n$. As an application we findnon-perturbative gauge enhancements of the heterotic string on singularCalabi--Yau manifolds and new non-perturbative dualities relatingheterotic compactifications on different manifolds.
