Bound States at Threshold in Supersymmetric Quantum Mechanics
M. Porrati, A. Rozenberg
We propose a general method that allows to detect the existence of normalizable ground states in supersymmetric quantum mechanical systems with non-Fredholm spectrum. We apply our…

Confinement in Covariant Gauges
Martin Schaden, Alexander Rozenberg
We examine the weak coupling limit of Euclidean SU(n) gauge theory in covariant gauges. Following an earlier suggestion, an equivariant BRST-construction is used to define the cont…

Topological Aspects of Gauge Fixing Yang-Mills Theory on S4
Laurent Baulieu, Alexander Rozenberg, Martin Schaden
For an space-time manifold global aspects of gauge-fixing are investigated using the relation to Topological Quantum Field Theory on the gauge group. The partition function o…
