Resumen de Characterizacion of the bivariate discrete distributions defined by a partial difference equations system

Ramón Gutiérrez Jáimez , Miguel Ángel Fajardo Caldera

• Conditions under which the solutions of a partial difference equations system can be probability functions are examined.

  When the coefficients of the system are polynomials then the partial difference equations system satisfied by generating functions associated to these distributions are easily obtained; they give useful recurrence relations for the moments. Three examples are given as well
