摘要

The fixed point theorem of cone expansion and compression of norm type for astrict set contraction operator is generalized by replacing the norms with a convex functionalsatisfying certain conditions. We then show how to apply our theorem to prove the existence ofa positive solution to a second-order differential equation with integral boundary conditionsin an ordered Banach space. An example is worked out to demonstrate the main results.
