Finite energy foliations and global dynamics in the restricted three-body problem
Lei Liu, Pedro A. S. Salomão
We establish a general criterion for the existence of finite energy foliations on contact three-manifolds with boundary, imposing strong global constraints on the associated Reeb f…
Super-Liouville equation with a spinorial Yamabe type term
Lei Liu, Mingjun Wei
In this paper, we study the super-Liouville equation with a spinorial Yamabe type term, a natural generalization of Liouville equation, super-Liouville equation and spinorial Yamab…
Asymptotic behaviors and dynamics of degenerate and mixed solitons for the coupled Hirota system with strong coherent coupling effects
Zhong Du, Mingke Qin, Lei Liu
In this work, we study the asymptotic behaviors and dynamics of degenerate and mixed solitons for the coupled Hirota system with strong coherent coupling effects in the isotropic n…
Gravitational lensing of the wormhole in the Eddington-inspired Born-Infeld spacetime with a cosmic string
Xin-Fei Li, Lei-Hua Liu, Yan-Zhi Meng +2
In this work we study gravitational lensing of the wormhole in the Eddington-inspired Born-Infeld (EiBI) spacetime that incorporates with a cosmic string. It was found that the pre…
Slowly rotating black hole in chiral scalar-tensor theory
Ze-Kai Yu, Lei Liu, Tao Zhu
The chiral scalar-tensor theory is an extension of the Chern-Simons modified gravity by introducing couplings between the first and second derivatives of the scalar field and parit…
Non-resonant Hopf Links Near a Hamiltonian Equilibrium Point
C. Grotta-Ragazzo, Lei Liu, Pedro A. S. Salomão
This paper is about the existence of periodic orbits near an equilibrium point of a two-degree-of-freedom Hamiltonian system. The equilibrium is supposed to be a nondegenerate mini…
