The Energy-Momentum-News Complex near Future Null Infinity
Jelle Hartong, Emil Have, Vijay Nenmeli +1
We study asymptotically flat vacuum solutions of general relativity in three and four dimensions, with an emphasis on the geometric structures that emerge near null infinity. We co…
Boundary Energy-Momentum Tensors for Asymptotically Flat Spacetimes
Jelle Hartong, Emil Have, Vijay Nenmeli +1
We consider 3D and 4D asymptotically flat spacetimes near future null infinity endowed with the most general allowed Carroll geometry. We define a boundary energy-momentum tensor b…
Mixmasters in Wonderland: Chaotic dynamics from Carroll limits of gravity
Gerben Oling, Juan F. Pedraza
We demonstrate that the Carroll limit of general relativity coupled to matter captures the chaotic mixmaster dynamics of near-singularity limits. Zooming in on the behavior of gene…
Setting the connection free in the Galilei and Carroll expansions of gravity
Jørgen Musaeus, Niels A. Obers, Gerben Oling
We obtain a Palatini-type formulation for the Galilei and Carroll expansions of general relativity, where the connection is promoted to a variable. Known versions of these large an…
