Query: Nondispersive decay for the cubic wave equation   We consider the hyperboloidal initial value problem for the cubic focusing
wave equation. Without symmetry assumptions, we prove the existence of a
co-dimension 4 Lipschitz manifold of initial data that lead to global solutions
in forward time which do not scatter to free waves.
