The authors use the coincidence degree theory developed by \textit{R. E. Gaines} and \textit{J. L. Mawhin} [``Coincidence degree, and nonlinear differential equations'', Lecture Notes in Mathematics. 568. Berlin-Heidelberg-New York, Springer-Verlag (1977; Zbl 0339.47031)] to derive easily verifiable criteria for the existence of positive periodic solutions for a generalized periodic semi-ratio-dependent predator-prey system with time delays and impulses.
