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…

On covariant and canonical Hamiltonian formalisms: Weakly Isolated Horizons
Alejandro Corichi, Juan D. Reyes, Tatjana Vukasinac
The Hamiltonian description of classical gauge theories is a well studied subject. The two best known approaches, namely the covariant and canonical Hamiltonian formalisms have rec…
