Fourth-order problems with nonlinear boundary conditions. (English) Zbl 1068.34013
The authors consider monotone-type and nonmonotone boundary conditions for fourth-order ordinary differential equations. In each of the two types of problems an existence result is established. The proofs (especially in monotone case) are technically complicated.
