研究测度链上非自治二阶Hamilton系统周期解的存在性问题.在非线性项次线性增长时,将这类系统的周期解转化为定义在一个适当空间上泛函的临界点,然后利用临界点理论建立了此类系统周期解的存在性结果.
The existence of periodic solutions for non-automous second order Hamiltonian systems on time scales with sublinear nonlinearity is investigated. The periodic solutions of the system are converted into the critical points of a functional defined on a proper space, and the existence of periodic solutions is proved by critical point theory.
