Annotation
The coupling constants and heavy particle operators are renormalized in a simple quantum field theoretical model with three types of fixed particle, interacting by exchange of relativistic bosons. A nonanalytic dependence is found between the renormalized coupling constant λ1 and the "internal" coupling constant λ02. The region of permissible values of the renormalized coupling constants is found for a given cut-off momentum (energy).
