PERIODIC BOUNDARY VALUE PROBLEMS FOR A CLASS OF SECOND-ORDER IMPULSIVE INTEGRO-DIFFERENTIAL EQUATIONS IN BANACH SPACES

摘要

This paper investigates periodic boundary value problems for a class of second-order nonlinear impulsive integro-differential equations of mixed type in a Banach space. By establishing a comparison result, criteria on the existence of maximal and minimal solutions are obtained. (C) 1997 Academic Press. [References: 5]
