Some examples in approximation on the unit disk by reciprocals of polynomials,ablished for a certain class of functions f analytic and nonzero in the disk |z|<1 and continuous on |z|≤1. Furthermore, we obtain the sharp degree of convergence for reciprocal polynomial approximation on |z|≤1 to functions f that are analytic on |z|≤1, nonzero in |z|<1, and vanish somewhere on |z|=1.

Properties of projections obtained by averaging certain polynomial interpolants,ach of which interpolates . at . equidistant points on the unit circle. The paper discusses properties of the projections so defined. Norms of these projections are calculated and the asymptotic behavior is characterized. Furthermore, these averages are used to approximate Laurent sections.

Ergebnisse der Chirurgie und Orthop?dieWhile Szeg? type asymptotics of orthonormal polynomials are classical, there has been a longstanding lack of corresponding results for L. extremal polynomials, p≠2. In particular, in a 1969 paper, Widom raised the question of p=∞. Here we fill some of the gaps for 1

Ergebnisse der Chirurgie und Orthop?dieIn this note it is shown that the asymptotic error estimate for weighted Chebyshev polynomials holds true under the same assumptions as those normaly required for the classical non-weighted case.

Ergebnisse der Chirurgie und Orthop?dieWe study existence and uniqueness problems associated with different definitions of rational interpolants with free or prescribed poles. The treatment of the subject is rather general; it includes interpolation at infinity, at confluent points, and interpolation in polar singularities.
