摘要
考虑非线性波方程时间周期解的存在性.应用变分法,在非线性项满足超线性增长且非单调的条件下,证明了非线性波方程时间周期解新的存在性结果.
This paper deals with the existence of time-periodic solutions for nonlinear wave equations.Some new existence result of time-periodic solutions for nonlinear wave equations was established via the variational method when the nonlinearity is superlinear and nonmonotone.
