Abstract: (Elsevier)
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 C P n = SU (n + 1)/ SU (n) × U (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.- algebra: Lie
