Abstract:In this talk, I will introduce two classes of Hamiltonian systems: LV Hamiltonian system in R^4 and Kolmogorov Hamiltonian systems in R^2 . Global dynamics is given for the LV Hamiltonian system in R^4 and all kinds of centers are obtained for a Kolmogorov Hamiltonian system in R^2. Moreover, the topological structures of real algebraic curves in R^2 or hypersurfaces in R^4 are discussed.
