A Weyl Entropy of Pure Spacetime Regions

摘要: We focus on the Penrose's Weyl Curvature Hypothesis in a general framework encompassing many specific models discussed literature. introduce candidate density for entropy pure spacetime perfect fluid regions and show that it is monotonically increasing time under very assumptions. Then we consider behavior of compact regions, which shown to be monotone as well suitable hypotheses, also maximal correspondence with vacuum static metrics. The minimal case too.
