摘要：

The existence of multiple positive solutions for the integral equation x(t) = integral(t+omega)(t) G(t, s) b(s)f(s, x(s - tau(1)(s)), ... , x(s - tau(n)(s)))ds is studied by using fixed point index theory. Using these results we obtain new results on the existence of multiple positive periodic solutions for some first order periodic functional differential equations. (C) 2008 Elsevier Inc.
