Multiple positive periodic solutions for a food-limited two-species ratio-dependent predator-prey patch system with delay and harvesting
By using Mawhin's coincidence degree theory, this paper establishes some sufficient conditions on the existence of four positive periodic solutions for a food-limited two-species ratio-dependent predator-prey patch system with delay and harvesting. Some novel techniques are employed to obta...
