Delay effect in the Nicholson's blowflies model with a nonlinear density-dependent mortality term [PDF]

open access: diamondElectronic Journal of Qualitative Theory of Differential Equations, 2017
This paper is concerned with a class of non-autonomous delayed Nicholson’s blowflies model with a nonlinear density-dependent mortality term. Under proper conditions, we prove that the positive equilibrium point is a global attractor of the addressed ...
