Abstract
We study curved and flat Bogomol’nyi-Prasad-Sommerfield (BPS)-domain walls in 5D, gauged supergravity and show that their effective dynamics along the flow is described by a generalized form of “fake supergravity.” This generalizes previous work in supergravity and might hint towards a universal behavior of gauged supergravity theories in supersymmetric domain wall backgrounds. We show that BPS-domain walls in 5D, supergravity can never be curved if they are supported by the supergravity scalar only. Furthermore, a purely Abelian gauge group or a purely semisimple gauge group can never lead to a curved domain wall, and the flat walls for these gaugings always exhibit a runaway behavior.
