Condensation of Matter and Trapped Surfaces in Quasi-Polar Gauge
Abstract
Description
We continue the investigation of formation of trapped surfaces in strongly curved , conformally flat geometries. Initial data in quasi-polar gauges rather then maximal ones are considered. This implies that apparent horizons coincide with minimal surfaces. Necessary and sufficient conditions for the formation of trapped surfaces are given. These results can be generalized to include the case with gravitational radiation. We found that mass of a body inside a fixed volume is bounded from above if geometry of a Cauchy slice is smooth.
