Free Field Representation of $osp(2|1)$ and $U_q(osp(2|1))$ and N=1 (q-)Superstring Correlation Functions

W. -S. Chung, A. Shafiekhani

The free field realization of irreducible representations of $\os$ is constructed, by a unified and systematic scheme. The $q$-analog of this unified scheme is used to construct $q…
