Relative Periodic Orbits in the Gutzwiller-type Anisotropic Kepler Problem and $n$ -body Problem

Xijun Hu, Yuwei Ou, Zhiwen Qiao +1

We study the relative periodic orbits in the Gutzwiller-type anisotropic Kepler problem, which is a generalized model derived from the classical Gutzwiller anisotropic Kepler probl…

Relative Periodic Orbits in the Spatial Anisotropic Kepler Problem

Xijun Hu, Yuwei Ou, Zhiwen Qiao

The spatial anisotropic Kepler problem comes from quantum mechanics, which models electron motion in semiconductors with donor impurities and depends on the anisotropic parameter $…

Three elliptic closed characteristics on the non-degenerate compact convex hypersurfaces in R^6

Lu Liu, Yuwei Ou

Let $Σ \subset R^{2 n}$ with $n \geq 2$ be any $C^{2}$ compact convex hypersurface. The stability of closed characteristics has attracted considerable attention in related resea…

ECH Constraints and Twist Dynamics in the Spatial Isosceles Three-Body Problem

Xijun Hu, Lei Liu, Yuwei Ou +2

We study dynamical constraints arising from Embedded Contact Homology (ECH) in the spatial isosceles three-body problem. For energies below the critical level, the dynamics on the…
