Abstract
We study the existence of solutions to the fourth order Lidstone boundary value problem
y(4)(t) = ƒ(y(t), -y" (t)),
y(0) = y"(0) = y"(1) = y(1) = 0.
By imposing growth conditions on ƒ and using a generalization of the multiple fixed point theorem by Leggett and Williams, we show the existence of at least three symmetric positive solutions. We also prove analogous results for difference equations.
