Existence and global exponential stability of positive almost periodic solutions for a delayed Nicholson's blowflies model

摘要

This paper concerns with a class of delayed Nicholson's blow-flies model with a nonlinear density-dependent mortality term. Under appropriate conditions, we establish some criteria to ensure that the solutions of this model converge globally exponentially to a positive almost periodic solution. Moreover, we give some examples and numerical simulations to illustrate our main results.
