Almost periodic solutions for a delayed Nicholson’s blowflies model with a nonlinear density-dependent mortality term

[摘要] A delayed Nicholson’s blowflies model with a nonlinear density-dependent mortality term is studied in this paper. Some sufficient conditions are obtained to guarantee the existence and global exponential stability of positive almost periodic solutions of this model. An example with numerical simulations is given to illustrate our main results. MSC: 34C25, 34K13.
