Description

We study the quantum hamiltonian reduction of the affine Lie superalgebra A(n,n-1)(1)=sl(n+1,n)(1)(n≥1), whose central charge is zero. After a BRST gauge fixing the model has a W algebra structure with N=2 superconformal symmetry. We show that this model is the N=2 coset model CPn=SU(n+1)/SU(n)xU(1) constructed by Kazama and Suzuki. We also discuss a topological field theoretical aspect of the SL(n+1,n) Wess-Zumino-Novikov-Witten model. (orig.)
