Gauges in the bulk

How to fix the gauges?

We present a special constraint structure that possesses both reducable and chain structure. Using our constraint structure, we show that the number of required gauge fixing conditions is just equal to the number of chains and the remaining requirements follow from consistency conditions. Electrodynamics and Yang-Mills theories are discussed as examples. e-mail address: [email protected] e-m...

Noncovariant Gauges in Simple Supergravity

A gauge-averaging functional of the axial type is studied for simple supergravity at one loop about flat Euclidean four-space bounded by a three-sphere, or two concentric three-spheres. This is a generalization of recent work on the axial gauge in quantum supergravity on manifolds with boundary. Ghost modes obey nonlocal boundary conditions of the spectral type, in that half of them obey Dirich...

- Type Singularities in Axial Gauges

The axial-gauge boson propagator contains 1/(η · k) p-type singularities. These singualarities have generally been treated by inventing prescriptions for them. We propose an alternative procedere for treating these singularities in the path-integral formalism using the known way of treating the 1/k 2n-type singularities in Lorentz-type gauges. For this purpose we use a finite field-dependent BR...
