Abstract
We examine the conditions for superconformal invariance and the specif ic form of the Kahler potential for a two-dimensional lagrangian model with N = 2 supersymmetry and superpotential gX(k). Away from the supe rconformal point we study the renormalization group flow induced by a particular class of Kahler 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.
