This paper deals with the existence and uniqueness of mild solutions for the initial value problems of abstract impulsive evolution equations in an ordered Banach space , , , , , , where is a closed linear operator, and is a nonlinear mapping. Under wide monotone conditions and measure of noncompactness conditions of nonlinearity , some existence and uniqueness results are obtained by using a monotone iterative technique in the presence of lower and upper solutions.
