Abstract:

This paper gives the existence and nonexistence of multiple solutions for the problem:

Δ2u=λu+|u|p-1u+μf(x), x∈Ω,μ>0;

u|Ω=0, u/n| Ω=0.

Where Ω is a smooth bounded domain in RN,λ∈R,μ>0,p=(N+4)/(N-4),N≥5,f(x) is a given nonnegative function.

Key words: Biharmonic equation, Critical exponent, Existence of multiple solutions
