TL;DR

This paper explores the widespread presence of warped anti-de Sitter spacetimes in three-dimensional (2,0) supergravity, proving their existence across various models and analyzing their supersymmetry properties.

Contribution

It demonstrates the existence of warped anti-de Sitter spacetimes in general (2,0) supergravity models and examines their supersymmetry characteristics.

Findings

Warped anti-de Sitter spacetimes are ubiquitous in (2,0) supergravity.

Existence is proven for models near a minimal setup.

Supersymmetry of these spacetimes and related orbifolds is analyzed.

Abstract

We comment on the ubiquity of the so-called warped anti-de Sitter spacetimes in three-dimensional (2,0) supergravity theory. By using isometry-invariant tensors and simple counting, we prove their existence for arbitrary $(2,0)$ supergravity models suitably defined close to a minimal model. We also analyze their offshell supersymmetry and the supersymmetry of two geometric orbifolds.
