Class Objectives
/Class Outline
This course provides an introduction to nonlinear two-point boundary value problems with fractional derivatives, a field that has seen rapid theoretical advancement and active discussion in recent years. Students will first master the construction of Green's functions and the fundamental concepts of the order topology. Building on this foundation, the course explores the properties of the first eigenvalue through the Krein-Rutman theorem, systematically examining the mechanisms that determine the existence, non-existence, uniqueness, and multiplicity of positive solutions. The ultimate goal is for students to acquire the analytical techniques necessary to logically elucidate the solution structures of nonlinear boundary value problems. 
Class Schedule 1. Introduction to the problems addressed in this course and explanation of Green's functions.
2. Introduction to the concepts of the order topology.
3. Introduction to the Krein-Rutman theorem and demonstration of the properties of the first eigenvalue.
4. Demonstration of the existence and non-existence of positive solutions.
5. Demonstration of the uniqueness and multiplicity of positive solutions.
