It studies the existence of nontrivial solutions to an asymptotically linear elliptic problem with nonlinear boundary conditions on Ω,where Ω is a bounded smooth domain in RN(N≥3)
and the nonlinear term f(x
u) is asymptotically linear with respect to u at infinity. By Ekeland’s variational principle and a variant version of Mountain Pass Theorem
it proves that there exist at least two nontrivial solutions if the non-negative parameter λ is small enough.
