On a periodic neutral delay logarithmic population model. (Chinese) Zbl 0953.92025

Summary: We obtain the sufficient conditions for the existence of a positive periodic solution to a periodic neutral delay logarithmic population model

N ˙(t)=N(t)r (t) - a (t) log N ( t - σ ) - b (t) (d/dt) log N ( t - τ ),

and give the sufficient conditions for the periodic solution to attract all other positive solutions.
