Dynamical systems with three degrees of freedom can be reduced to the study of a fourdimensional mapping. We consider here, as a model problem, the mapping given by the following equations: left\{ begin{gathered} x_1 = x_0 + a_1 {text{ sin (}}x_0 {text{ + }}y_0 {text{)}} + b{text{ sin (}}x_0 {text{ + }}y_0 {text{ + }}z_{text{0}} {text{ + }}t_{text{0}} {text{)}} \ y_1 = x_0 {text{ + }}y_0 \ z_1 = z_0 + a_2 {text{ sin (}}z_0 {text{ + }}t_0 {text{)}} + b{text{ sin (}}x_0 {text{ + }}y_0 {text{ + }}z_{text{0}} {text{ + }}t_{text{0}} {text{) (mod 2}}π {text{)}} \ t_1 = z_0 {text{ + }}t_0 \ right. We have found that as soon asb≠0, i.e. even for a very weak coupling, a dynamical system with three degrees of freedom has in general either two or zero isolating integrals (besides the usual energy integral).
