摘要：

Operator quantization of the WZNW theory invariant with respect to an affine Lie algebra (g) over cap with a constrained (u) over cap(l)(d) subalgebra is performed using Dirac's procedure. Upon quantization the initial energy-momentum tensor is replaced by the g/u(1)(d) coset construction. The s (u) over cap(2) WZNW theory with a constrained (u) over cap(1) current is equivalent to the su(2)/u(1) conformal field theory. (C) 1998 Elsevier Science B.V.
