The Yang--Mills gauge field theory in the context of a generalized BRST--formalism including translations
O. Moritsch, M. Schweda, T. Sommer
We discuss the algebraic renormalization of the Yang--Mills gauge field theory in the presence of translations. Due to the translations the algebra between Sorella's $\d$--operator…

Local gravitational supersymmetry of Chern-Simons theory in the vielbein formalism
S. Emery, O. Moritsch, M. Schweda +2
We discuss the Chern-Simons theory in three-dimensional curved space-time in the vielbein formalism. Due to the additional presence of the local Lorentz symmetry, beside the diffeo…

BRST cohomology of Yang-Mills gauge fields in the presence of gravity in Ashtekar variables
O. Moritsch, M. Schweda, T. Sommer +2
The BRST transformations for the Yang-Mills gauge fields in the presence of gravity described by Ashtekar variables are obtained by using the so-called Maurer-Cartan horizontality…
