| Abstract: | In this paper, by using of some new technics and theory of topological degree,the existence of positive periodic solution for the neutral delay model in popula-tion of the form is studied.A new result is obtained,and results related to references are improved. |
| Keywords: | Neutral type delay model in population positive periodic solution topological degree |
