SU(2) Gauge Theory in Covariant (Maximal) Abelian Gauges
Martin Schaden
The local covariant continuum action of an SU(2) gauge theory in covariant Abelian gauges is investigated. It describes the critical limit of an Abelian Lattice Gauge Theory (LGT)…

Mass Generation in Continuum SU(2) Gauge Theory in Covariant Abelian Gauges
Martin Schaden
The local action of an SU(2) gauge theory in general covariant Abelian gauges and the associated equivariant BRST symmetry that guarantees the perturbative renormalizability of the…

Quantization in the Presence of Gribov Ambiguities
Martin Schaden
The non-perturbative validity of covariant BRST-quantization of gauge theories on compact Euclidean space-time manifolds is reviewed. BRST-quantization is related to the constructi…
