Idea

An S-brane is a spacelike brane, hence a brane instanton.

For instance in 11-dimensional supergravity S2-branes are membrane instantons.

Properties

Near horizon geometry

The near horizon geometry of an Spp-brane involves hyperbolic manifolds (Gutperle-Strominger 02 (5.20), Chen-Galtsov-Gutperle 02, A., Roy 02, p. 3-4), the isometry group being Iso(p+1)×SO(d−p−2,1)Iso(p+1) \times SO(d-p-2,1)

• M-theory on hyperbolic manifolds
