摘要

Algebraic properties of the Becchi-Rouet-Stora-Tyutin (BRST) symmetry associated to the twisted gauge symmetry occurring in the κ -Poincaré invariant gauge theories on the κ -Minkowski space are investigated. We find that the BRST operation associated to the gauge invariance of the action functional can be continuously deformed together with its corresponding Leibniz rule, into a nilpotent twisted BRST operation, leading to a twisted BRST symmetry algebra which may be viewed as a noncommutative analog of the usual Yang-Mills BRST algebra.
