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.

Key words: differential equation with delay, impulse, fixed point theorem, periodic solution, existence
