Sufficient conditions for the existence of positive periodic solutions of a class of neutral delay models

By using the theory of coincidence degree, the existence of positive periodic solutions is studied for the neutral model with periodic delaysN^'(t)=N(t)a(t)[email protected](t)N(t)[email protected]?"i"="1^nb"i(t)N([email protected]"i(t))[email protected]?"i"="1^nc"i(t)N^'([email protected]"i(t)).Our results extend and improve existing results, and have further applications in population dynamics.
