Abstract: | Operator quantization of the WZNW theory invariant with respect to an affine Lie algebra
with a constrained
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
WZNW theory with a constrained
current is equivalent to the su(2)/u(1) conformal field theory. |
