On the Existence and Uniqueness of a Positive Solution to a Boundary-Value Problem of the Sturm–Liouville Type for a Nonlinear Ordinary Differential Equation
摘要
Using the fixed point theorem in partially ordered sets, we obtain sufficient conditions for the existence of a unique positive solution to a boundary-value problem of the Sturm–Liouville type for a nonlinear ordinary differential equation, and give an example illustrating the results obtained.
