The authors study a neutral delay model of population growth NEWLINE\[NEWLINEN'(t)=N(t)[a(t)-\beta(t)N(t)-b(t)N(t-\tau(t))-c(t)N'(t-\tau(t))],NEWLINE\]NEWLINE where all parameters are nonnegative continuous \(T\)-periodic functions. They provide sufficient conditions under which the equation admits at least one positive \(T\)-periodic solution.
