In this paper we focus on three fixed point theorems and an integral equation. Schaefer's fixed point theorem will yield a Tperiodic solution of z(t) = a(t) + D(t, s)g(s, z(s)) ds 6, if D and g satisfy certain sign conditions independent of their magnitude. A combination of the contraction mapping t
