σ) dt.

The improper integral (3.22) in view of solutions (2.10) and (2.15) is calculated numerically. For parameter (3.14) the conditions for the manifolds to intersect are given by

J I (for the area 0A ),

J I (for the area 1A ). (3.25)

Criteria (3.25) defi ne behaviour of the perturbed system (3.17) in a vicinity of separatrixes.
