Domain Wall and de Sitter Solutions of Gauged Supergravity

TL;DR

This paper discovers BPS domain wall solutions in gauged supergravities, including models with non-compact gauge groups, some of which feature unstable de Sitter solutions alongside stable domain walls.

Contribution

It presents new BPS domain wall solutions in gauged supergravities with non-compact gauge groups, expanding the understanding of possible solutions in these theories.

Findings

Existence of BPS domain wall solutions in various gauged supergravities.

Identification of models with both unstable de Sitter and stable domain wall solutions.

Extension to theories with non-compact gauge groups.

Abstract

BPS domain wall solutions of gauged supergravities are found, including those theories which have non-compact gauge groups. These include models that have both an unstable de Sitter solution and stable domain wall solutions.
