In this paper,the existence of sign-changing solutions to a nonlinear third-order two-point boundary value problem is researched by applying new fixed point theorems with the lattice structure.By combining the eigenvalues and the algebraic multiplicity,the existence of solutions at least three nontrivial solutions which are a positive solution,a sign-changing solution,and a negative solution is given.
