Description
We give formulas for density of the measure of orthogonality for orthonormal polynomials with unbounded recurrence coefficients. The formulas involve limit of appropriately scaled Turán determinants or Christoffel functions. Exact asymptotics of the polynomials and numerical examples are also provided.
