Abstract: On the basis of the method of guiding functional families and the method of Lyapunov vector functions we obtain sufficient condition for the existence of Poisson bounded solutions, as well as a sufficient condition for the existence of partially Poisson bounded solutions of systems of differential equations.

Keywords: vector Lyapunov function, rotation of the vector field, guiding function, guiding function, guiding functional family, Poisson boundedness of solution, partial Poisson boundedness of solution.
