Completeness of Coherent States Associated with Self-Similar Potentials   and Ramanujan's Integral Extension of the Beta Function
  A decomposition of identity is given as a complex integral over the coherent states associated with a class of shape-invariant self-similar potentials. There is a remarkable connection between these coherent states and Ramanujan's integral extension of the beta function.
