Existence of positive periodic solutions for a class of Gilpin-Ayala ecological models with discrete and distributed time delays
Abstract In this paper, we deal with a class of Gilpin-Ayala ecological models with discrete and distributed time delays. By employing a fixed point theorem of strict-set-contraction and inequality techniques, some sufficient conditions for the existence of periodic solutions are established. As an...
