RT info:eu-repo/semantics/article T1 Attractors in almost periodic Nicholson systems and some numerical simulations A1 Villarragut, Víctor M. A1 Sanz Gil, Ana María K1 Delay equations, Population dynamics, Persistence, Global attractor, Almost periodic Nicholson systems AB The existence of a global attractor is proved for the skew-product semiflowinduced by almost periodic Nicholson systems and new conditions are given for theexistence of a unique almost periodic positive solution which exponentially attractsevery other positive solution. Besides, some numerical simulations are included toillustrate our results in some concrete Nicholson systems.
