摘要:

In this article, we focus on the eigenvalue problem of the following linear biharmonic equation in RN:
2uαu+λg(x)u = 0 with uH2(RN), u ≠0, N ≥ 5. (*)
Note that there are two parameters and α in it, which is different from the usual eigen-value problems. Here, we consider λ as an eigenvalue and seek for a suitable range of parameter α, which ensures that problem (*) has a maximal eigenvalue. As the loss of
strong maximum principle for our problem, we can only get the existence of non-trivial so-lutions, not positive solutions, in this article. As an application, by using these results, we studied also the existence of non-trivial solutions for an asymptotically linear biharmonic
equation in RN.
