Monotone and convex positive solutions for fourth-order multi-point boundary value problems

Abstract

Abstract The existence results of multiple monotone and convex positive solutions for some fourth-order multi-point boundary value problems are established. The nonlinearities in the problems studied depend on all order derivatives. The analysis relies on a fixed point theorem in a cone. The explicit expressions and properties of associated Green's functions are also given. MSC: 34B10; 34B15.
