Multiple positive solutions for nonlinear first-order impulsive dynamic equations on time scales with parameter

Abstract

By using the Leggett-Williams fixed point theorem, the existence of three positive solutions to a class of nonlinear first-order periodic boundary value problems of impulsive dynamic equations on time scales with parameter are obtained. An example is given to illustrate the main results in this paper.
