Soft Algebras in AdS $_{4}$ from Light Ray Operators in CFT $_{3}$

Ahmed Sheta, Andrew Strominger, Adam Tropper +1

Flat Minkowski space (M $^{4}$ ) and AdS $_{4}$ can both be conformally mapped to the Einstein cylinder. The maps may be judiciously chosen so that some null generators of the $\mathcal{I…

EVERY CFT $_{3}$ HAS AN $L_{I^} w_{1 + \infty}$ SYMMETRY

Andrew Strominger, Hongji Wei

Recently a one-parameter family of deformed $L w_{1 + \infty}$ soft symmetry algebras, denoted $L_{I^} w_{1 + \infty}$ , acting on tree-level gravitational theories i…

Frames and Slicings for Angular Momentum in Post-Minkowski Scattering

Samuel E. Gralla, Kunal Lobo, Hongji Wei

In relativistic physics, angular momentum is paired with a lesser known conserved quantity, the "mass moment", which appears as the time-space components of the angular momentum te…
