Abstract.

In this paper, we make an attempt to modify the classic construction of partition of unity (general method of sewing together local smooth objects into a global one) to include the case of objects invariant along a given smooth flow. A class of flows is determined which allow such a construction. A general scheme is presented of obtaining a non-local first integral by sewing together a set of local integrals.

Keywords:

dynamical systems, flows, first integrals.
