Reduction of Coupling Parameters
Abstract
The general theory of the reduction in the number of coupling parameters is discussed. The method involves renormalization group invariant relations between couplings. It is more general than the imposition of symmetries. There are reduced theories with no known symmetry. The reduction scheme is finding many applications. Discussed in some detail are the construction of gauge theories with ``minimal'' coupling for YangMills and matter fields, and the GaugeYukawa Unification within N=1 supersymmetric GUT's.
