“…ii nonnegative constants. The pointwise convergence of the Fourier series associated to such an inner product was studied when µ 0 is the Jacobi measure (see also [20,21]). On the other hand, the asymptotics for orthogonal polynomials with respect to the Sobolev-type inner product (1) with µ 0 ∈ M(0, 1), c k belong to suppµ \ [−1, 1], and A k are complex diagonal matrices such that a (k) 1+N k ,1+N k = 0, was solved in [2].…”
