A bstractWe show that interpreting the inverse AdS3 radius 1/l as a Grassmann variable results in a formal map from gravity in AdS3 to gravity in flat space. The underlying reason for this is the fact that ISO(2, 1) is the Inonu-Wigner contraction of SO(2, 2). We show how this works for the Chern-Simons actions, demonstrate how the general (Banados) solution in AdS3 maps to the general flat space solution, and how the Killing vectors, charges and the Virasoro algebra in the Brown-Henneaux case… 

Scalar fields in 3D asymptotically flat higher-spin gravity

In this work we construct a novel associative algebra and use it to define a theory of higher-spin gravity in (2 + 1)-dimensional asymptotically flat spacetimes. Our construction is based on a

BMS/GCA redux: towards flatspace holography from non-relativistic symmetries

A bstractThe asymptotic group of symmetries at null infinity of flat spacetimes in three and four dimensions is the infinite dimensional Bondi-Metzner-Sachs (BMS) group. This has recently been shown

It is shown that the BMS algebra in 3 dimensions is the same as the 2D Galilean conformal algebra (GCA) which is of relevance to nonrelativistic conformal symmetries and proposes a general BMS-GCA correspondence.

Diffeomorphisms preserve spacetime singularities, whereas higher spin symmetries need not. Since three-dimensional de Sitter space has quotients that have big-bang/big-crunch singularities and since

A first derivation of the Bekenstein-Hawking entropy of 3D flat cosmological horizons is provided in terms of the counting of states in a dual field theory, exactly reproducing the bulk entropy in the limit of large charges.
