Canonical Description of T-duality with NSNS Background

TL;DR

This paper derives generalized T-duality rules for backgrounds with NSNS B-fields using canonical formalism and extends the analysis to non-relativistic string theories.

Contribution

It provides a systematic derivation of generalized Buscher's rules for T-duality in NSNS backgrounds and applies the method to non-relativistic strings.

Findings

Derived generalized T-duality rules with NSNS B-fields.

Extended T-duality analysis to non-relativistic string theories.

Clarified the canonical formalism approach to T-duality.

Abstract

We study T-duality with non-zero components of NSNS two form field along directions we dualize with the help of canonical formalism. As a result of this procedure we determine generalized Buscher's rules. We also apply the same procedure to the case of non-relativistic string.
