Existence of \(n\) positive solutions to a singular beam equation rigidly fixed at left and simply supported at right. (English) Zbl 1199.34085
Summary: By applying the Krasnosel’skii fixed point theorem on a cone, the existence of \(n\) positive solutions is established for a nonlinear fourth-order two-point boundary value problem with singular nonlinearity.
