报告题目： Black hole memory and blackhole information
地点：理科生命大楼多功能厅A513
摘要：
Strominger et. al. found the relations between gravitational memory effect and the soft theorem in quantum field theory. In the Nonlinear level, he also found the relation between supertranslation and Kac-Moody Ward identities. Later, in a long paper with Hawking and Perry, they argue the similar memory effect also should be existed on horizon if there is black hole and the supercharge on horizon should has relation with the black hole information problem. In this informal talk, I just want to discuss these paper with everyone and try to get more understanding on them. We have construct some simple toy model to check their idea.
