Query: A family of martingales generated by a process with independent
  increments   An explicit procedure to construct a family of martingales generated by a
process with independent increments is presented. The main tools are the
polynomials that give the relationship between the moments and cumulants, and a
set of martingales related to the jumps of the process called Teugels
martingales
