| Abstract: | Spherical, time-dependent geometrical structures in an inflationary RW background are derived from the Einstein equations,
using a constraint on the energy-momentum tensor which is an extension of the one expected for inflation. The possibility
of dynamical wormholes and other spherical structures are explored in the framework of the solutions.
