摘要：

We generalize the recent free field realization of SU(N) current algebras by considering more general (super)groups G and their (super)kahlerian cosets G/H which are (super)hermitian symmetric spaces. The method consists of introducing free fields corresponding to the (super)kahlerian coset and building the currents in a manner similar to Wigner's construction of the Poincare group from generalized "orbital" and "spin" degrees of freedom. We then show that our parametrization of the currents yields free field representations for the superconformal n = 2 Kazama-Suzuki-type models as well as the related topological quantum field theories.
