    "abstract": "We discuss medium modifications of the unitarized pion-pion interaction in\nthe nuclear medium. We incorporate both the effects of chiral symmetry\nrestoration and the influence of collective nuclear pionic modes originating\nfrom the p-wave coupling of the pion to delta-hole configurations. We show in\nparticular that the dropping of the sigma meson mass significantly enhances the\nlow energy structure created by the in-medium collective pionic modes.",
