Gravitational radiations of generic isolated horizons and nonrotating dynamical horizons from asymptotic expansions

摘要: Instead of using a three-dimensional analysis on quasilocal horizons, we adopt four-dimensional asymptotic expansion to study the next order contributions from nonlinearity general relativity. From similarity between null infinity and proper reference frames are chosen compatible constant spinors for an observer measure energy-momentum flux near horizons. In particular, focus Bondi-Sachs gravitational radiation horizons compare our results with Ashtekar-Kirshnan formula. The generic isolated nonrotating dynamical discussed in this paper.
