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…
BRST BMS4 Symmetry and its Cocycles from Horizontality Conditions
Laurent Baulieu, Tom Wetzstein
The BRST structure of the extended Bondi-Metzner-Sachs symmetry group of asymptotically flat manifolds is investigated using the recently introduced framework of the Beltrami field…
Leaf of Leaf Foliation and Beltrami Parametrization in dimensional Gravity
Laurent Baulieu
This work shows the existence of a d>2 dimensional covariant "Beltrami vielbein" that generalizes the d=2 situation. Its definition relies on a sub-foliation Σ^{ADM}_{d-1}=Σ_{d-3}\…
