The existence of invariant curves of a kind of almost periodic twist mappings
Yingdu Dong, Xiong Li
In this paper, we are concerned with the existence of invariant curves of the planar twist mappings where the perturbations are almost periodic. As an application, the existence of…
Boundedness of solutions in impulsive Duffing equations with polynomial potentials and time dependent coefficients
Yanmin Niu, Xiong Li
In this paper, we are concerned with the impulsive Duffing equation with impulsive effects $x(t_{j}+)=x(t_{j}-),\ x…
Persistence of invariant tori in integrable Hamiltonian systems under almost periodic perturbations
Peng Huang, Xiong Li
In this paper we are concerned with the existence of invariant tori in nearly integrable Hamiltonian systems \begin{equation*} H=h(y)+f(x,y,t), \end{equation*} where $y\in D\subset…
The stability of equilibrium solutions of periodic Hamiltonian systems in the case of degeneracy
Nina Xue, Xiong Li
In this paper we are concerned with the stability of equilibrium solutions of periodic Hamiltonian systems with one degree of freedom in the case of degeneracy, which means that th…
Almost periodic solutions for an asymmetric oscillation
Peng Huang, Xiong Li, Bin Liu
In this paper we study the dynamical behaviour of the differential equation \begin{equation*} x''+ax^+ -bx^-=f(t), \end{equation*} where ,\ , …
Entire Solutions for the Classical Competitive Lotka-Volterra System with Diffusion in the Weak Competition Case
Yang Wang, Xiong Li
In this paper we are concerned with the entire solutions for the classical competitive Lotka-Volterra system with diffusion in the weak competition. For this purpose we firstly ana…
Invariant curves of smooth quasi-periodic mappings
Peng Huang, Xiong Li, Bin Liu
In this paper we are concerned with the existence of invariant curves of planar mappings which are quasi-periodic in the spatial variable, satisfy the intersection property, $\math…
Invariant curves of almost periodic twist mappings
Peng Huang, Xiong Li, Bin Liu
In this paper we are concerned with the existence of invariant curves of planar twist mappings which are almost periodic in a spatial variable. As an application of this result to…
