Abstract.
This paper considers Hermite—Fejér and Grünwald interpolation based on the zeros of the Chebyshev polynomials for the real rational system P n (a 1 , . . . , a n ) with the nonreal poles in {a}n k=1 \(\subset\) C\[-1,1] paired by complex conjugation. This extends some well-known results of Fejér and Grünwald for the classical polynomial case.
