3d gravity in Bondi-Weyl gauge: charges, corners, and integrability
3d gravity in Bondi-Weyl gauge: charges, corners, and integrability
We introduce a new gauge and solution space for three-dimensional gravity. As its name Bondi-Weyl suggests, it leads to non-trivial Weyl charges, and uses Bondi-like coordinates to allow for an arbitrary cosmological constant and therefore spacetimes which are asymptotically locally (A)dS or flat. We explain how integrability requires a choice …
