Description
The construction of braneworlds localizing massless gravity on subsurfaces of spacetimes with infinite transverse spaces has remained an open problem. There have even been some "no-go" theorems claiming to show that such constructions are not possible. The talk will present a resolution of this problem simply based upon a hyperbolic solution of type IIA theory with a superposed Neveu-Schwarz 5-brane. Gravity is bound to the brane surface owing to the existence of a single normalizable bound state of the transverse space Laplacian.
