| Abstract: | By means of the Leggett Williams fixed point theorem,the existence of positive solutions was investigated for functional diff erential equations with impulses and delay, with new sufficient conditions for the existence of, at least, three positive periodic solutions about the differential equations obtained. |
| Keywords: | differential equation with delay impulse fixed point theorem periodic solution existence |
