    "abstract": "Changes in the meson-nucleon coupling constant and the vertex form factor in\nnuclear matter are studied in a modified Skyrme Lagrangian including the\nsigma-meson field that satisfies the scale invariance. Renormalization of the\naxial-vector coupling constant, and the nucleon mass are studied in a\nconsistent model. The results are consistent with the empirical evidence. A\ncalculation of pi N commutator, sigma-term, indicates that the medium changes\nits magnitude considerably.",
