Non-Perturbative Structure in Heterotic Strings from Dual F-Theory Models

TL;DR

This paper explores the duality between heterotic string models and F-theory in eight dimensions, revealing how non-perturbative features influence perturbative descriptions and proposing a modified T-duality linking M and F-theories.

Contribution

It introduces a method to construct heterotic models dual to F-theory and proposes a new form of T-duality based on non-perturbative structures in eight-dimensional string theories.

Findings

Identification of moduli space overlaps between heterotic and F-theory models

Trace of non-perturbative features in perturbative regimes

Proposal of a modified T-duality linking M and F-theories

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.
