Keywords:
integrability; Henstock-Kurzweil integral; ordered Banach space; order cone; chain; fixed point; functional integral equation; Volterra; Cauchy problem; ordered Banach space; fixed point
Summary:
A fixed point theorem in ordered spaces and a recently proved monotone convergence theorem are applied to derive existence and comparison results for solutions of a functional integral equation of Volterra type and a functional impulsive Cauchy problem in an ordered Banach space. A novel feature is that equations contain locally Henstock-Kurzweil integrable functions.
