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…
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 ,\ , …
Periodic solutions of semilinear Duffing equations with impulsive effects
Yanmin Niu, Xiong Li
In this paper we are concerned with the existence of periodic solutions for semilinear Duffing equations with impulsive effects. Firstly for the autonomous one, basing on Poincaré-…
Periodic solutions of sublinear impulsive differential equations
Yanmin Niu, Xiong Li
In this paper, we consider sublinear second order differential equations with impulsive effects. Basing on the Poincaré-Bohl fixed point theorem, we first will prove the existence…
