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.
