title: The existence of positive periodic solutions of a generalized N-species Gilpin-Ayala impulsive competition system.
abstract: In this paper, the existence of positive periodic solutions of a class of periodic -species Gilpin-Ayala impulsive competition systems is studied. By using the continuation theorem of coincidence degree theory, a set of easily verifiable sufficient conditions is obtained. Our results are general enough to include some known results in this area.
