%0 Journal Article %T On non-absolute functional Volterra integral equations and impulsive differential equations in ordered Banach spaces %A Seppo Heikkila %A Seppo Seikkala %J Electronic Journal of Differential Equations %D 2008 %I Texas State University %X In this article we derive existence and comparison results for discontinuous non-absolute functional integral equations of Volterra type in an ordered Banach space which has a regular order cone. The obtained results are then applied to first-order impulsive differential equations. %K HL integrability %K Bochner integrability %K ordered Banach space %K dominated convergence %K monotone convergence %K integral equation %K boundary value problem %U http://ejde.math.txstate.edu/Volumes/2008/103/abstr.html
