Exact Duality Symmetries in CFT and String Theory

TL;DR

This paper explores the concept of duality symmetries in conformal field theory and string theory, providing new insights especially for non-compact cases and arguing for the persistence of duality as a symmetry.

Contribution

It extends previous work by presenting additional results on duality in non-compact cases and argues for the continued presence of duality as a symmetry in these scenarios.

Findings

Duality persists as a symmetry in non-compact cases.

Additional results on duality in non-compact conformal field theories.

Supports the idea that duality is a fundamental symmetry in string theory.

Abstract

There is substancial overlap with hepth-9211081. More results are presented for duality in the non-compact case. It is argued that duality persists as a symmetry also in that case.
