Abstract
We study the periodic boundary value problems for nonlinear integro-differential equations of Volterra type with Carathéodory functions. For two situations relative to lower and upper solutions α and β∶α≤ß or ß≤α, the existence of solutions and the monotone iterative method for establishing extreme solutions are considered.
