Positive periodic solutions of functional differential equations with infinite delay

Changxiu Song — 2008

Annales Polonici Mathematici

The author applies a generalized Leggett-Williams fixed point theorem to the study of the nonlinear functional differential equation $x^{'} (t) = - a (t, x (t)) x (t) + f (t, x_{t})$ . Sufficient conditions are established for the existence of multiple positive periodic solutions.
