Full Description
In gauge theories, quantization can only be performed in certain fixed gauges, but physical gauges often lead to mathematical complications in the theory. In this volume recent results in noncovariant gauge fixing (including supersymmetry) and renormalizability are thoroughly discussed. It is the first comprehensive presentation of this subject written by leading experts in the field.
