NONLOCAL CONSERVED CURRENTS FOR NSR STRING IN AdS_3 BACKGROUND

摘要

The propagation of NSR string AdS_3 directX S~3 x R_4 background is envisaged and the worldsheet action is expressed in in terms of the variables on the group manifolds SL(2, R) and SU(2) as 1 + 1 dimensional σ-models with Wess-Zumino terms. We appeal to superspace formulation for construction of infinite set of nonlocal conserved currents for NSR string on the above background.
