Abstract

We investigate the number of the solutions for the biharmonic boundary value problem with a variable coefficient non-linear term. We get a theorem which shows the existence of m weak solutions for the biharmonic problem with variable coefficient. We obtain this result by using the critical point theory induced from the invariant function and invariant linear subspace.
