Abstract:
In this article, we investigate the fourth-order
four-point nonhomogeneous Sturm-Liouville boundary-value
problem
where
and
and
are
nonnegative parameters. We obtain sufficient conditions for
the existence and uniqueness of positive solutions.
The dependence of the solution on the parameters
and
is also studied.
