Resumo(s)
We study a large class of orthogonal polynomials, containing the semi-classical
symmetric orthogonal polynomials of class two. We show difference equations for the
recurrence coefficients of the orthogonal polynomials as well as for related quantities.
Some of these recurrences are identified with discrete Painlevé equations.
