Abstract: In this paper, the initial value problems of second order ordinary differential equations in Banach spaces are discussed. By using the monotone iterative technique, some existence and uniqueness theorems for solutions are obtained.

Key words: ordered Banach spaces, measures of noncompactness, mixed monotone operators
