Asymptotic behavior inside the disk for Lebesgue Sobolev orthogonal polynomialsKeywords: Orthogonal polynomials , Difference equations , Sobolev inner products , Measures on the unit circle Abstract: In the present paper we study the behavior, inside and on the unit disk, of the monic orthogonal polynomials with respect to the following Sobolev inner product where is a finite positive Borel measure on with infinite support and is the normalized Lebesgue measure. Since strong asymptotics for the monic Sobolev orthogonal polynomials are well-known outside the unit disk, our aim, in this paper, is to study when the asymptotic formula can be extended up to the boundary and inside the disk.
