This paper investigates the existence of positive solutions for a class of singular -Laplacian fourth-order
differential equations with integral boundary conditions. By using the fixed point theory in cones, explicit range for and
is derived such that for any and lie in their respective interval, the existence of at least one positive
solution to the boundary value system is guaranteed.
