摘要：

In this paper, we consider first-order neutral differential equations with a parameter and impulse in the form of d/dt[x(t) - cx(t - gamma)] = -a(t)g(x(h(1)(t)))x(t) + lambda b(t)f(x(h(2)(t))), t not equal t(j); Delta[x(t) - cx(t - gamma)] - I-j (x(t)), t - t(j), j is an element of Z(+). Leggett-Williams fixed point theorem, we prove the existence of three positive periodic solutions.
