Abstract
In this paper, we investigate the existence and nonexistence of positive solutions for a system of nonlinear higher-order ordinary differential equations with Riemann-Stieltjes integral boundary conditions which contain some positive constants.
Keywords: Higher-order differential equations, integral boundary conditions, positive solutions, existence, nonexistence
