Abstract:
This article concerns the fourth-order elliptic equation
where
is a parameter,
and
has nonempty interior. Under some mild assumptions,
we establish the existence of two nontrivial solutions.
Moreover, the concentration of these solutions is explored on the set
as
.
As an application, we give the similar
results and concentration phenomenona for the above problem with concave
and convex nonlinearities.
