Data: | 2017 |
Resum: | In this paper first we give the sufficient and necessary conditions in order that two classes of polynomial Kolmogorov systems in \R_ ^4 are Hamiltonian systems. After we study the integrability of these Hamiltonian systems in the Liouville sense. Finally, we investigate the global dynamics of the completely integrable Lotka--Volterra Hamiltonian systems in \R_ ^4. As an application of the invariant subsets of these systems, we obtain topological classifications of the 3-submanifolds in \R_ ^4 defined by the hypersurfaces a x y b z w c x^2 y d x y^2 e z^2 w f z w^2= constant. |
