摘要:

In this paper, we study a class of p(x)-biharmonic equations with Navier boundary condition. Using the mountain pass theorem, fountain theorem, local linking theorem and symmetric mountain pass theorem, we establish the existence of at least one solution and infinitely many solutions of this problem, respectively.

关键词: p(x)-biharmonic, variable exponent, Cerami condition, critical points, vari-ational method
