Periodic Solutions for a Semi-Ratio-Dependent Predator-Prey System with Delays on Time Scales
This paper is devoted to the existence of periodic solutions for a semi-ratio-dependent predator-prey system with time delays on time scales. With the help of a continuation theorem based on coincidence degree theory, we establish necessary and sufficient conditions for the existence of periodic sol...
