Abstract
The dispersion technique is used to describe three-particle final-stat e interaction. The decay eta --> 3 pi is considered as an example. Int egral equations for the amplitude of the decay eta --> 3 pi are obtain ed using the two-particle unitarity condition, S- and P-wave interacti ons of pions being taken into account.
