Euclidean super Yang-Mills theory on a hyper-K"ahler manifold
D. M"ulsch, B. Geyer
The construction of a cohomological gauge theory on an hyper-K"ahler eight-fold, whose group theoretical descrition was given by Blau and Thompson, is performed explicitly.
N_T=8, D=2 Hodge-type cohomological gauge theory with global SU(4) symmetry
B. Geyer, D. Mülsch
We show that the partially topological twisted N=16, D=2 super Yang-Mill theory gives rise to a N_T=8 Hodge-type cohomological gauge theory with global SU(4) symmetry.
OSp(1,2)-covariant Lagrangian quantization of irreducible massive gauge theories
B. Geyer, P. M. Lavrov, D. Mülsch
The osp(1,2)-covariant Lagrangian quantization of general gauge theories is formulated which applies also to massive fields. The formalism generalizes the Sp(2)-covariant BLT appro…
Symmetry properties of massive gauge theories in nonlinear background gauges: Background dependence of Green functions
B. Geyer, D. M"ulsch
Nonabelian gauge theories with a generic background field A_mu in nonlinear gauges due to Delbourgo and Jarvis are investigated. The A_mu-dependence is completely determined by the…
