| Description: | [DPS Seminar] Dr. Rituparno Goswami (University of Kwa-Zulu Natal, Durban) -- Holography in GR: 4-dimensional spacetimes from 2-dimensional conformal null data |
| Date: | Wednesday, Jan 10, 2018 |
| Time: | 2 p.m. - 3 p.m. |
| Venue: | G02, Lecture Hall Complex |
| Details: | We investigate whether the holographic principle proposed in string theory has a classical counterpart in general relativity. We show that there is a partial correspondence: at least in the case of vacuum Petrov type D spacetimes that admit a non-trivial Killing tensor, which encompass all the astrophysical black hole spacetimes, there exists a one-to-one correspondence between gravity in bulk and a 2-dimensional classical conformal Euclidean scalar field on a null boundary. |
