Cyclicity of rigid centres on centre manifolds of three-dimensional systems

چکیده
We work with polynomial three-dimensional rigid differential systems. Using the Lyapunov constants, we obtain lower bounds for cyclicity of known centers on their center manifolds. Moreover, an example a quadratic from which is possible to bifurcate 13 limit cycles, new bound

Dynamical Systems on Three Manifolds Part II: Three-Manifolds, Heegaard Splittings and Three-Dimensional Systems
The global behaviour of nonlinear systems is extremely important in control and systems theory since the usual local theories will only give information about a system in some neighbourhood of an operating point. Away from that point, the system may have totally different behaviour and so the theory developed for the local system will be useless for the global one. In this paper we shall consid...

متن کاملOn three dimensional stellar manifolds
It is well known that a three dimensional (closed, connected and compact) manifold is obtained by identifying boundary faces from a stellar ball a ⋆ S. The study of S/ ∼, two dimensional stellar sphere S with 2-simplexes identified in pairs leads us to the following conclusion: either a three dimensional manifold is homeomorphic to a sphere or to a stellar ball a⋆S with its boundary 2-simplexes...
متن کاملPERIODIC SOLUTIONS OF CERTAIN THREE DIMENSIONAL AUTONOMOUS SYSTEMS
There has been extensive work on the existence of periodic solutions for nonlinear second order autonomous differantial equations, but little work regarding the third order problems. The popular Poincare-Bendixon theorem applies well to the former but not the latter (see [2] and [3]). We give a necessary condition for the existence of periodic solutions for the third order autonomous system...
