Quantum properties of general gauge theories with composite and external fields
S. Falkenberg, B. Geyer, P. Moshin
The generating functionals of Green's functions with composite and external fields are considered in the framework of BV and BLT quantization methods for general gauge theories. Th…
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…
On the Structure of Quantum Gauge Theories with External Fields
S. Falkenberg, B. Geyer, P. Lavrov +1
We consider generating functionals of Green's functions with external fields in the framework of BV and BLT quantization schemes for general gauge theories. The corresponding Ward…
Gauge Invariant Formulation and Bosonisation of the Schwinger Model
J. Kijowski, G. Rudolph, M. Rudolph
The functional integral of the massless Schwinger model in dimensions is reduced to an integral in terms of local gauge invariant quantities. It turns out that this approac…
Path integral quantization of electrodynamics in dielectric media
M. Bordag, K. Kirsten, D. V. Vassilevich
In the present paper we study the Faddeev-Popov path integral quantization of electrodynamics in an inhomogenious dielectric medium. We quantize all polarizations of the photons an…
The heat kernel coefficient on a manifold with boundary
Klaus Kirsten
In this letter we present the calculation of the heat kernel coefficient of the heat operator trace for a partial differential operator of Laplace type on a compact Riemann…
