Abstract
Let μ be a compactly supported positive measure on the real line, with associated orthogonal polynomials p n . Without any global restrictions such as regularity, we discuss convergence in measure for
We also establish convergence a.e.for sufficiently sparse subsequences of Christoffel function ratios.
