SUPERSPACE SUPERVORTICES

We present the theory describing supersymmetrical vortices in the curv ed superspace of the (1, 0) supergravity. The action is defined as a ( 1, 0) locally supersymmetric SU(2)/U(1) coset perturbed by the cosmolo gical constant-like term. The perturbation is such that it preserves t he integrability of the coset model. Because of supersymmetry the pert urbed theory is an exact quantum system provided a proper dilaton is t aken into account. The exact value of the dilaton is determined in the supersymmetric case by the quasi-classical background of the bosonic coset.
