  "abstract": "We consider a resonant level coupled to a chiral Luttinger liquid which can be realized, e.g., at a fractional quantum Hall edge. We study the dependence of the occupation probability n of the level on its energy \\epsilon for various values of the Luttinger-liquid parameter g. At g<1/2 a weakly coupled level shows a sharp jump in n(\\epsilon) at the Fermi level. As the coupling is increased, the magnitude of the jump decreases until \\sqrt{2g}, and then the discontinuity in n(\\epsilon) disappears. We show that n(\\epsilon) can be expressed in terms of the magnetization of a Kondo impurity as a function of magnetic field.",
