Abstract:
We consider the perturbed biharmonic equations
and
where
is the biharmonic operator,
,
is the Sobolev critical exponent,
Q(x) is a bounded positive function. Under some mild conditions on
V and f, we show that the above equations have at least one
nontrivial solution provided that
,
where the bound
is formulated in terms of N, V, Q and f.
