Local BRST cohomology and Seiberg-Witten maps in noncommutative Yang-Mills theory
Glenn Barnich, Friedemann Brandt, Maxim Grigoriev
We analyze in detail the recursive construction of the Seiberg-Witten map and give an exhaustive description of its ambiguities. The local BRST cohomology for noncommutative Yang-M…
Asymptotically anti-de Sitter space-times: symmetries and conservation laws revisited
Glenn Barnich, Friedemann Brandt, Kim Claes
In this short note, we verify explicitly in static coordinates that the non trivial asymptotic Killing vectors at spatial infinity for anti-de Sitter space-times correspond one to…
Comments on the Gauge Fixed BRST Cohomology and the Quantum Noether Method
Glenn Barnich, Tobias Hurth, Kostas Skenderis
We discuss in detail the relation between the gauge fixed and gauge invariant BRST cohomology. We showed previously that in certain gauges some cohomology classes of the gauge-fixe…
Boundary charges in gauge theories: using Stokes theorem in the bulk
Glenn Barnich
Boundary charges in gauge theories (like the ADM mass in general relativity) can be understood as integrals of linear conserved n-2 forms of the free theory obtained by linearizati…
