|Title:||COSMIC WALLS FROM GRAVITATIONAL COLLAPSE|
|Abstract:||The formation of plane cosmic walls of negligible thickness from the collapse of smooth inhomogeneous plane-symmetric distributions of matter is considered. Two models with different asymptotic behaviors far from the wall in formation are constructed. In the first, the fluid far from the wall is anisotropic, with pressures proportional to density. The second model describes an asymptotically isotropic ideal gas in isentropic flow. Even though both models start from matter distributions with positive density and pressures everywhere, it is found that, during the collapse, negative pressures (tensions) appear within the wall in formation.|
