    "abstract": "We study effects of the medium polarization on superfluidity in symmetric\nnuclear matter in a relativistic formalism. An effect of the liquid-gas\ninstability is emphasized. We examine two types of decomposition of the nucleon\npropagator; the standard Feynman-density and the particle-hole-antiparticle\nones. In both cases, the medium polarization effect is determined by a\ncharacteristic cancellation among the \\sigma, the longitudinal \\omega, and the\n\\sigma-\\omega mixed polarizations. The instability leads to increase of pairing\ngap. Around the saturation density that is free from the instability the medium\npolarization enhances pairing gap in the former case whereas reduces in the\nlatter. At the lowest density that is also free from the instability the gap\nincreases in both cases.",
