Positive Solutions for Boundary Value Problems of Second-Order Functional Dynamic Equations on Time Scales
Criteria are established for existence of least one or three positive solutions for boundary value problems of second-order functional dynamic equations on time scales. By this purpose, we use a fixed-point index theorem in cones and Leggett-Williams fixed-point theorem.
