|Title:||Space-time Defects: Open And Closed Shells|
|Abstract:||A class of space-times with zero curvature tensor except on a hypersurface is derived; in particular, metrics that represent parabolic and cylindrical plates, and parabolic, spherical, spheroidal, and toroidal shells are studied. The motion of particles around and inside the defects is considered. The interpretation of some of these space-times as wormholes is briefly considered. © 1995 American Institute of Physics.|
