Non-Perturbative Structure in Heterotic Strings from Dual F-Theory Models
arXiv:hep-th/9901028 · doi:10.1016/S0370-2693(99)00420-7
Abstract
We examine how to construct explicit heterotic string models dual to F-theory in eight dimensions. In doing so we learn about where the moduli spaces of the two theories overlap, and how non-perturbative features leave traces on a purely perturbative level. We also propose a modified T-duality linking M and F-theories based on non-perturbative structures of string theories in eight dimensions.
