Four Positive Almost Periodic Solutions to a Nonautonomous Bi-directional Consumer-Resource System with Impulses and Harvesting Terms

In this paper,an delayed impulsive nonautonomous bi-directional consumer-resource system with harvesting terms is investigated. By using a continuation theorem based on coincidence degree theory and inequality analysis technique,some sufficient conditions for the existence of at least four positive almost periodic solutions for this system are obtained. The results generalize and improve the related results of early literature.
