Homotopy kinematic algebras at null infinity

Year: 2025

Type: article

Abstract: We present the first formulation of a homotopy algebra adapted to a 1 / r expansion near future null infinity ( I + ). Focusing on self-dual Yang-Mills theory in Bondi coordinates, we demonstrate that imposing the homotopy algebra relations naturally yields the physically consistent fall-off behavior of the fields near I + . Furthermore, we employ this framework to systematically construct kinematic algebras, uncovering novel infinite families of such algebras that satisfy the Jacobi identity on slices near I + .
