Regular SBrane Backgrounds
Abstract
We construct timedependent Sbrane solutions to the supergravity field equations in various dimensions which (unlike most such geometries) do not contain curvature singularities. The configurations we consider are less symmetric than are earlier solutions, with our simplest solution being obtained by a simple analytical continuation of the Kerr geometry. We discuss in detail the global structure and properties of this background. We then generalize it to higher dimensions and to include more complicated field configurations—like non vanishing scalars and antisymmetric tensor gauge potentials—by the usual artifice of applying duality symmetries.
