Ground ring for the two-dimensional NSR string

We discuss the BSRT quantization of two-dimensional N = 1 supergravity coupled to super-conformal matter with c ̂ ⩽ 1 in the conformal gauge. The physical states are computed as BRST cohomology. In particular, we consider the ring structure and associated symmetry algebra for the two-dimensional sup...

Description
Summary:We discuss the BSRT quantization of two-dimensional N = 1 supergravity coupled to super-conformal matter with c ̂ ⩽ 1 in the conformal gauge. The physical states are computed as BRST cohomology. In particular, we consider the ring structure and associated symmetry algebra for the two-dimensional superstring ( c ̂ = 1) .
