Type	JournalPaper
Keywords	p(x)-Biharmonic; variable exponent; critical points; minimum principle; fountain theorem; dual fountain theorem.
Abstract	In this article, we study the following problem with Navier boundary conditions (j ujp(x)􀀀2 u) + jujp(x)􀀀2u = jujq(x)􀀀2u + juj (x)􀀀2u in ; u = u = 0 on @ : where is a bounded domain in RN with smooth boundary @ , N  1. p(x); q(x) and (x) are continuous functions on ,  and  are parameters. Using variational methods, we establish some existence and non-existence results of solutions for this problem.
