Constructing Holography for Flat Spacetimes

Arjun Bagchi
U. Edinburgh.


After a broad introduction to holography, I focus on our recent formulation of holography for flat-space. The discussion would be mainly in three bulk and two boundary dimensions and the construction would be primarily based on the analysis of symmetries. We formulate flat holography as a limit of the usual AdS/CFT correspondence. This would lead to a novel understanding of 3d cosmological horizons in terms of a dual field theory. Time permitting, I would also discuss a novel proposal we call Flat-space Chiral Gravity.
