摘要：

In Foulquie et al. (1999) [2], Li and Marcellan (1996) [4], Marcellan and Moral (2002) [5], the relative asymptotic behavior of orthogonal polynomials with respect to a discrete Sobolev-type inner product on the unit circle was studied. In this paper, we propose an alternative approach to this problem based on the Uvarov spectral transformation. (C) 2011 Elsevier Ltd. All rights reserved.
