BV-BRST Noether theorem
Glenn Barnich, Laurent Baulieu, Marc Henneaux +1
The BRST Noether theorem, or ``Noether's 1.5 theorem'', asserts the triviality of the BRST Noether current. We provide two proofs of this theorem that are both valid without restri…

BRST Noether Theorem and Corner Charge Bracket
Laurent Baulieu, Tom Wetzstein, Siye Wu
We provide a proof of the BRST Noether 1.5th theorem, conjectured in [JHEP 10 (2024) 055], for a broad class of rank-1 BV theories including supergravity and 2-form gauge theories.…

BRST Covariant Phase Space and Holographic Ward Identities
Laurent Baulieu, Tom Wetzstein
This paper develops an enlarged BRST framework to treat the large gauge transformations of a given quantum field theory. It determines the associated infinitely many Noether charge…
