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…
pychop: Emulating Low-Precision Arithmetic in Numerical Methods and Neural Networks
Erin Carson, Xinye Chen
Motivated by the growing demand for reduced-precision arithmetic in computational science, we exploit lower-precision emulation in Python{--}widely regarded as the dominant program…
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…
