Qualitative analysis of the anisotropic Kepler problem

The Kepler Problem with Anisotropic Perturbations

We study a 2-body problem given by the sum of the Newtonian potential and an anisotropic perturbation that is a homogeneous function of degree −β, β ≥ 2. For β > 2, the sets of initial conditions leading to collisions/ejections and the one leading to escapes/captures have positive measure. For β > 2 and β 6= 3, the flow on the zero-energy manifold is chaotic. For β = 2, a case we prove integrab...

Periodic Orbits of the Planar Anisotropic Kepler Problem

In this paper we prove that at every energy level the anisotropic problem with small anisotropy has two periodic orbits which bifurcate from elliptic orbits of the Kepler problem with high eccentricity. Moreover we provide approximate analytic expressions for these periodic orbits. The tool for proving this result is the averaging theory.

این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...

On the Complexity of the Anisotropic Kepler Problem and the Planar Isosceles Three Body Problem

We show how to associate a computation to certain 2 degree of freedom hamiltonian systems, and use this to discuss the level of complexity of certain problems in the dynamics of these systems. A type of Turing machine over the reals can be identified, embedded in these systems. 1.Introduction. In two articles [1], C.Moore has explored a class of simple dynamical systems, and, in particular, has...
