Abstract:
We prove the existence and uniqueness, and study the global behavior of
a positive continuous solution to the superlinear second-order differential
equation
where a,b are nonnegative constants such that a+b>0, A is a
continuous function on
,
positive and continuously
differentiable on
such that 1/A is integrable on
[0,1] and
.
Here
, for
and
g(t,s) is a nonnegative continuous function satisfying suitable
integrability condition. Our Approach is based on estimates of the Green's
function and a perturbation argument. Finally two illustrative examples are
given.
