Using the fixed point theorem due to Avery and Peterson we establish the existence criteria of at least three positive solutions to the problem. As an application an example is given to illustrate the result. The interesting points are that not only do we consider third-order p-Laplacian dynamic equation but also the nonlinear term f is involved with the first-order delta derivative of the unknown function.

Introduction The theory of dynamic equations on time scales was introduced by Stefan Hilger in 1988 1 . This theory has attracted many researchers attention and interest since it cannot only unify differential and difference equations but also provides accurate information of phenomena that manifest themselves partly in continuous time and partly in discrete time. In addition time-scale calculus would allow exploration of a variety of situations in economic
