Asymptotics for the simplest generalized Jacobi polynomials recurrence   coefficients from Freud's equations: numerical explorations.
  Generalized Jacobi polynomials are orthogonal polynomials related to a weight function which is smooth and positive on the whole interval of orthogonality up to a finite number of points, where algebraic singularities occur. The influence of these singular points on the asymptotic behaviour of the recurrence coefficients is investigated.
