Multiple solutions for fourth order $m$-point boundary value problems with sign-changing nonlinearity

Using a fixed point theorem in ordered Banach spaces with lattice structure founded by Liu and Sun, this paper investigates the multiplicity of nontrivial solutions for fourth order $m$-point boundary value problems with sign-changing nonlinearity. Our results are new and improve on those in the lit...
