    "abstract": "We derive a set of coupled four-dimensional integral equations for the\n$NN-\\pi NN$ system using our modified version of the Taylor method of\nclassification-of-diagrams. These equations are covariant, obey two and\nthree-body unitarity and contain subtraction terms which eliminate the\ndouble-counting present in some previous four-dimensional $NN-\\pi NN$\nequations. The equations are then recast into a from convenient for computation\nby grouping the subtraction terms together and obtaining a set of two-fragment\nscattering equations for the amplitudes of interest.",
