Abstract
Several new existence theorems on positive, negative, and sign-changing solutions for the following fourth-order beam equation are obtained: , ; , where . In particular, an infinitely many sign changing solution theorem is established. The method of the invariant set of decreasing flow is employed to discuss this problem.
