# Non-abelian T-folds

## TL;DR

This paper explores the conditions for non-abelian T-duality to be viewed as a sequence of abelian T-dualities and proposes describing the topology of non-abelian T-duals using T-folds with explicit O(d, d) transformations.

## Contribution

It introduces a framework to understand non-abelian T-duals as T-folds, providing explicit O(d, d) transformations for their topology.

## Key findings

- Non-abelian T-duality can be decomposed into abelian T-dualities under certain conditions.
- The topology of non-abelian T-duals can be described using T-folds.
- Explicit O(d, d) transformations are provided for gluing the dual space.

## Abstract

We discuss the conditions under which non-abelian T-duality can be considered as a chain of abelian T-dualities. Motivated by these results, we propose that the topology of a non-abelian T-dual should be phrased in the language of T-folds, and give the explicit O(d, d) transformations which can be used to glue the dual space.
