Existence of periodic solutions for image-Laplacian systems Original Research Article

In this paper, by using minimax methods in critical point theory, we obtain some existence theorems for periodic solutions of p(t)p(t)-Laplacian system View the MathML source{(|u′(t)|p(t)−2u′(t))′+∇F(t,u(t))=0,u(0)−u(T)=u′(0)−u′(T)=0 Turn MathJax on and our results generalize some existed theorems.
