利用临界点理论研究非自治p(t)-Laplacian 系统周期解的存在性,在具有超线性增长非线性项时,根据对称山路定理,得到了系统无穷多个周期解存在的充分条件。
Using critical point theory, the author studied the existence of periodic solutions for non-autonomous p(t)-Laplacian systems with superlinear nonlinearity.Some sufficient conditions for the existence of infinitely many periodic solutions were obtained via the symmetric mountain pass theorem.
