Relativistic Faddeev-Yakubovsky four-nucleon scattering equations are derived including a 3-body force. We present these equations in the momentum space representation. The quadratic integral equations using the iteration method, in order to obtain boosted potentials and 3-body force, are demonstrated.

This paper deals with the derivation of the relativistic four-body Yakubovsky equations, building on the author's (and others') previous work of transforming the (three-body) Fadeev equations to a relativistic framework. The paper is well-written, though necessarily dense in formalism. It is a useful statement of the derivations and the final results of the relativistic equations and should be published in the proceedings. The language has many small errors, but is a readable kind of English as found in scientific papers and will cause no problem in understanding on the part of the reader.
