报告摘要:

 Gravitational radiation plays an important role in astrophysics. Based on the fact that our universe is expanding, some developments on gravitational radiation in asymptotically de Sitter spacetime have been obtained recently. In this talk, we will introduce the Bondi-Sachs (BS) framework and show its applications in asymptotically de Sitter spacetime. Moreover, some open problems will also be mentioned. This talk is based on joint works with Zhoujian Cao and Jiliang Jing.
