摘要
By applying the well known Leggett-Williams multiple fixed point theorem and fixed point theorem of cone expansion and compression, this paper investigates the existence of multiple positive solutions of periodic boundary value problems for first order differential equations. Meanwhile, two examples are worked out to demonstrate the main results. (C) 2007 Elsevier Ltd. All rights reserved.
