✦ Synopsis

We construct five massive deformations of the unique nine-dimensional N = 2 supergravity, each with two parameters. All of these deformations have a higher-dimensional origin via Scherk-Schwarz reduction and correspond to gauged supergravities. The gauge groups we encounter are SO(2), SO(1, 1) + , R, R + and the unique two-dimensional non-Abelian Lie group CR 1 , which consists of scalings and translations in one dimension.

We make a systematic search for two classes of vacuum solutions: maximally symmetric solutions with constant scalars and half-supersymmetric domain wall solutions. In the first category we find explicit solutions in the form of (non-supersymmetric) de Sitter space solutions. In the second category we find precisely the three classes of domain wall solutions that were given in an earlier work.
