By using a fixed point theorem of mixed monotone operators in cone, this paper studied a fourth-order nonlinear singularboundary value problem, namely a class of elastic beam equation.
This paper discusses the existence of multiple positive solutions of a class of nonlinear singularboundary value problems by means of the fixed point index Theorem on cones.
