Abstract

We consider general charged Kasner-like solutions for the theory of five-dimensional supergravity coupled to Abelian vector multiplets in arbitrary space-time signature. These solutions, depending on the choice of coordinates, can be thought of as generalisations of Melvin/Rosen cosmologies, flux-branes and domain walls.
