Li, Yongkun Positive periodic solutions for a periodic neutral differential equation with feedback control. (English) Zbl 1092.34033 Nonlinear Anal., Real World Appl. 6, No. 1, 145-154 (2005). Sufficient conditions are derived for the existence of periodic solutions of a periodic single species model governed by a neutral differential equation with feedback control. The approach is based on the abstract continuation theory for \(k\)-contractions.
