Zl. Wei, PERIODIC BOUNDARY-VALUE-PROBLEMS FOR 2ND-ORDER IMPULSIVE INTEGRODIFFERENTIAL EQUATIONS OF MIXED-TYPE IN BANACH-SPACES, Journal of mathematical analysis and applications, 195(1), 1995, pp. 214-229
In this paper, the author obtains an existence theorem of minimal and
maximal solutions for the periodic boundary value problems of second o
rder impulsive integrodifferential equations of mixed type in Banach s
pace by means of the monotone iterative technique and cone theory base
d on a comparison result. (C) 1995 Academic Press, Inc.
