| Abstract: | We express the vacuum expectation value of the SU(3)k parafermion fields by that of two bosons and SU(3)k current algebra. When k = 1,2,3, the SU(3)k current algebra becomes an inner product of a unitary representation, and T(z), W(3)(z) are equivalent to "quasiself-adjoint" operators in this represen tation. |
