Uri Kol
We show that the Einstein equations in the vacuum are invariant under an duality symmetry which rotates the curvature 2-form into its tangent space Hodge dual. Akin to elec…

Supertranslation-Invariant Dressed Lorentz Charges
Reza Javadinezhad, Uri Kol, Massimo Porrati
We present an explicit formula for Lorentz boosts and rotations that commute with BMS supertranslations in asymptotically flat spacetimes. Key to the construction is the use of inf…
