报告摘要：

Black holes can carry soft hairs, which provides a possible resolution of the black hole information paradox (BHIP). I will talk about derivations of soft photon and soft gluon theorems in the near horizon region of the Schwarzschild black hole from the Ward identity of the near horizon large gauge transformation. The flat spacetime theorems can be recovered as a limiting case of the curved spacetime. The soft photons and gluons on the horizon are indeed soft hairs on black holes. This accomplishes the triangle equivalence on the black hole horizon. Using electric soft hair as a tool, we can derive the Page curve consistent with the unitary evolution of black holes. I will discuss more progress and problems related to the role of soft hair in understanding the BIHP.
