“…When k = 1, it becomes the classical Nicholson's blowflies equation which has been extensively studied in the literature [2,6,28,30,32,38,42] and references cited therein. For the multiple-patch Nicholson's blowflies model, corresponding results can be found in [10,11,17,18,27,40,41] and references cited therein. When k ̸ = 1, equation ( 2) appears as a model for the process of generation and degeneration of red blood cells [14,37].…”
