Mirror Symmetry as a Gauge Symmetry

TL;DR

This paper demonstrates that mirror symmetry in string theory can be interpreted as a gauge symmetry within the moduli space of certain backgrounds, suggesting a broader applicability to other geometries like Calabi-Yau manifolds.

Contribution

It introduces the novel idea that mirror duality acts as a gauge symmetry in string theory moduli space, expanding the conceptual understanding of dualities.

Findings

Mirror duality is a gauge symmetry in N=2 backgrounds on group manifolds.

Conjecture on extending this gauge symmetry interpretation to Calabi-Yau backgrounds.

Abstract

It is shown that in string theory mirror duality is a gauge symmetry (a Weyl transformation) in the moduli space of $N=2$ backgrounds on group manifolds, and we conjecture on the possible generalization to other backgrounds, such as Calabi-Yau manifolds.
