    "abstract": "We study the parity-violating pion-nucleon coupling $G_\\pi$ in the framework\nof a realistic three flavor Skryme model. We find a sizeable enhancement of\n$G_\\pi \\simeq 0.8 ... 1.3 \\cdot 10^{-7}$ compared to previous calculations in\ntwo-flavor models with vector mesons. This strangeness enhancement stems from\ninduced kaon fields of the chiral soliton and the non-monotoneous dependence on\nsymmetry breaking of the nucleon matrix element of the flavor singlet piece of\nthe operator associated with these induced fields. Both features are sensitive\nto four quark operators including an $\\bar s s$ pair.",
