Positive Solutions for a Singular Superlinear Fourth-Order Equation with Nonlinear Boundary Conditions

We show the existence of positive solutions for a singular superlinear fourth-order equation with nonlinear boundary conditions. where λ > 0 is a small positive parameter, is continuous, superlinear at ∞, and is allowed to be singular at 0, and h: [0, 1] ？ [0, ∞) is continuous. Our approach is based on the fixed-point result of Krasnoselskii type in a Banach space
