| Abstract: | In this paper, we study two types of neutral functional differential equations with finite or unbounded distributed deviating arguments. By Banach contraction princi-ple, we obtain some sufficient conditions for the existence of positive solutions to such equations. |
| Keywords: | neutral functional differential equation positive solutions fixed point finite or unbounded distributed delay |
