Query: On the Green's function and iterative solutions of Loop Quantum
  Cosmology   Here we shall find the green's function of the difference equation of loop
quantum cosmology. To illustrate how to use it, we shall obtain an iterative
solution for closed model and evaluate its corresponding Bohmian trajectory.
