    Abstract
    We show that, for Morse – Smale diffemorphism $f\colon M^n\to M^n$, $n\geqslant 4$, the closure of one- and $(n-1)$-dimensional separatrices in a basin of a sink point $\omega$ forms a trivial frame that contrasts with the case $n=3$. This result is a first step in the solution of problems of topological classification, embedding in a flow and existence of energy functions for such diffeomorphisms.
    Keywords: Morse – Smale diffeomorphisms, trivial frame of separatrices, topological classification

    Abstract
    We obtain properties of three-dimensional phase space and dynamics of Morse–Smale diffeomorphism that led to existence of at least one heteroclinical curve in non-wandering set of the diffeomorphism. We apply this result to solve a problem of existence of separators in magnetic field of plasma.
    Keywords: Morse – Smale cascades, heteroclinic curves, mapping torus, locally trivial bundle, separators of magnetic field
