The asymptotic setting involves self-dual gravity, its Weyl Bianchi identities, conservation laws, and a suitable choice of asymptotic frame. Geiller's conjecture. The conservation…

The fields $A$ and its conjugate momentum $\pi$ satisfy the free-electrodynamics equations of motion and Poincaré transformations near spatial infinity. Parity-condition reduction…

The BMS group is the asymptotic symmetry group of asymptotically flat spacetimes at null infinity. Its elements act on past and future null infinity, and the gravitational S-matrix…

Let $\mathfrak{Max}_3$ denote the infinite-dimensional Maxwell algebra considered in the source, and let its deformations be the corresponding deformed Lie algebras. Let a three-di…

The three-dimensional Maxwell and AdS-Lorentz supergravity theories presented in the cited works admit new infinite-dimensional structures obtained through the corresponding…

The $\mathcal{N}$-extended Maxwell superalgebra is the finite-dimensional symmetry algebra underlying the three-dimensional Chern–Simons supergravity theories considered here. The…

In asymptotically-flat spacetimes, null infinity carries conservation laws associated with the asymptotic structure of quantum gravity. Scattering-matrix constraint conjecture. The…

At future null infinity $\mathcal{I}^+$ of Minkowski space, consider a non-Abelian gauge theory with gauge group $G$. The theory may have charge or color flux through…
