Abstract
We examine the conditions for superconformal invariance and the specific form of the Kähler potential for a two-dimensional lagrangian model with N = 2 supersymmetry and superpotential gX k . Away from the superconformal point we study the renormalization group flow induced by a particular class of Kähler potentials. We find trajectories which, in the infrared, reach the fixed point with a central charge whose value is that of the N = 2, A k −1 minimal model.
