Three dimensional Bondi Metzner Sachs invariant two dimensional field theories as the flat limit of Liouville theory
... As a nontrivial two-dimensional conformal field theory, Liouville theory is ubiquitous in theoretical physics (see e.g. [1–3] for reviews). In particular, in the context of three- dimensional ...

Three dimensional fractional spin gravity
... The aim of this paper is to demonstrate within a simple class of models, namely topo- logical models of Chern-Simons type which we refer to as fractional-spin gravities, how standard tensorial higher-spin gravities can ...

Asymptotically flat spacetimes in three dimensional higher spin gravity
... Higher spin gravity [1–3] has recently motivated a flurry of activity. In the case of d ≥ 4 dimensions, the consistency of the theory necessarily requires the presence of a negative cosmological constant, which naturally ...

A virtual three dimensional model of Las Meninas: paradox or mirror image?
... Interestingly, King Charles II’s probate list of assets makes mention of a huge mirror (3.5 × 2 varas, i.e. 2.9 × 1.7 m) hanging in the King’s bedchamber at the time of his death [26]. In the royal painters’ studio, ...
