Title: Double solutions of three-point boundary-value problems for
       second-order differential equations

Author: Johnny Henderson (Baylor Univ., Waco, Texas, USA)

Abstract: 
 A double fixed point theorem is applied to yield the
 existence of at least two nonnegative solutions for the three-point
 boundary-value problem for a second-order differential equation,
 $$\displaylines{
 y'' + f(y)=0,\quad 0 \leq t \leq 1,\cr
 y(0) =0,\quad  y(p) - y(1) = 0,
 }$$
 where $0 < p < 1$ is fixed, and $f:\mathbb{R} \to [0, \infty)$ is
 continuous.
