Ukr. Mat. Zh. - 2002. - 54, № 10. - pp. 1336-1347
We consider one method for the introduction of local coordinates in a neighborhood of an m-dimensional invariant torus of a dynamical system of differential equations in the Euclidean space R n in dimensions satisfying the inequalities m + 1 < n ≤ 2m.
