In hep-th/0409174, Lin, Lunin and Maldacena constructed a set of regular 1/2 BPS geometries in IIB theory. These remarkable ‘bubbling AdS’ geometries have a natural interpretation as duals of chiral primary operators with weight Δ=J in N=4 super-Yang–Mills theory. Although these geometries have been assumed to be complete, from a purely supergravity point of view, additional 1/2 BPS configurations...
We construct time dependent S-brane solutions in gauged and ungauged supergravities in various dimensions. The supergravity solutions we find are all special cases of solutions in gauged supergravities with symmetric potentials. We discuss some properties of these solutions and their relation to topological black holes in anti-de Sitter spaces.
