Abstract
We consider perturbed Volterra integral operator equations of the form
where \(\psi :{\mathscr {C}}([0,1])\rightarrow {\mathbb {R}}\) is a linear functional. By utilizing a nonstandard order cone and an associated nonstandard open set, we demonstrate the existence of at least one positive solution to this problem under some more general conditions previously seen in the literature. As a related problem we consider the one-dimensional p-Laplacian equation
subject to the nonlocal boundary conditions
where \(\varphi _p(z):=|z|^{p-2}z\), for \(p>2\), is the one-dimensional p-Laplacian.
