Existence and nonexistence results for fifth-order multi-point boundary value problems involving integral boundary condition

Filomat, 2023
In this paper, by using the classical compression-expansion fixed point theorem of Krasnoselskii, we study the existence and nonexistence of monotone and convex positive solutions for a nonlinear fifth-order differential equation with multi-point and integral boundary condition.
