Soft charges and zero modes at null boundaries
DuÅ¡an ÄorÄeviÄ, Dušan Đorđević, Olivera Miskovic +3
The paper investigates how a global zero-mode ambiguity on null boundaries, including null infinity and black‑hole horizons, changes the canonical structure of field theories and i…

Integrability in Asymptotic Symmetries of Spacetime: the scenario
Corentin Vitel
The paper revisits and extends the construction of an integrable hierarchy associated with the BMS₃ asymptotic symmetry algebra, building a bi‑Hamiltonian structure, Nijenhuis oper…

as the Frame Algebra of Kerr Soft Dressing
Gabriel Menezes
The paper shows that the Veneziano–Vilkovisky supertranslation, a large diffeomorphism linking Bondi and intrinsic frames, generates a parity‑alternating tower of soft modes that e…
