摘要：
Recently, a noncompact regularization of the SU(2) gauge theory on a lattice has been investigated numerically. The results have been interpreted as an indication that the physical volume is larger than in the Wilson theory with the same number of sites. In its original formulation the noncompact regularization is directly applicable to U(n) theories for any n but to SU(n) theories for n=2 only. In this paper we extend it to SU(n) for any n and investigate some of its properties.
