    "abstract": "We derive the dynamical equations which consistently couple the four--body\n($\\pi$NNN) system to the underlying three--nucleon system. Our treatment can be\nconsidered the proper generalization of the Afnan--Blankleider equations for\nthe coupled NN--$\\pi$NN system. The resulting connected--kernel equation\nresembles in structure the Yakubovskii--Grassberger--Sandhas equation for the\nstandard four--body problem, but involves 24 chain--labelled components (rather\nthan the usual 18 ones) and allows for a consistent evaluation of reaction\namplitudes involving $\\pi$ absorption/production.",
