Heterotic-type IIA duality with fluxes

TL;DR

This paper explores a non-perturbative duality between heterotic string theory on K3 x T^2 with fluxes and type IIA string theory on SU(3) structure manifolds, extending previous duality analyses.

Contribution

It demonstrates that type IIA on SU(3) structure manifolds can reproduce a subset of heterotic flux configurations, advancing understanding of flux dualities.

Findings

Type IIA on SU(3) structure manifolds accounts for heterotic fluxes.

Extends previous duality analysis to include fluxes.

Provides insights into non-perturbative heterotic/type IIA duality.

Abstract

In this paper we study a possible non-perturbative dual of the heterotic string compactified on K3 x T^2 in the presence of background fluxes. We show that type IIA string theory compactified on manifolds with SU(3) structure can account for a subset of the possible heterotic fluxes. This extends our previous analysis to a case of a non-perturbative duality with fluxes.
