Abstract:
In this article we study a well-known boundary value problem
With
in place of
,
many authors studied the existence
of positive solutions of both the positone problems with
and
the semi-positone problems for
.
It is well-known that the standard
method successfully applied to the semi-positone problem with
does not work for
in the same setting. We treat the latter as a
problem with a sign-changing term rather than a semi-positone problem.
We apply Krasnosel'skii's fixed point theorem [4] to obtain positive solutions.
