Evaluation of Bartnik's quasilocal mass function
Piotr Koc
Bartnik's definition of gravitational quasilocal energy is analyzed. For a wide class of systems Bartnik's function is given by the ADM mass of some vacuous extension. As an exampl…

Condensation of Matter and Trapped Surfaces in Quasi-Polar Gauge
Piotr Koc
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 con…
