"On
Barycentric Rational Interpolation"

By

Alexander Goncharov

(Bilkent University)

Abstract: J-P. Berrut suggested in 1988 so-called barycentric rational interpolation.
Afterward, many papers and numerous computational experiments demonstrated the
effectiveness of this method in comparison to the polynomial interpolation. In
particular, the logarithmic growth (with respect to the number of nodes) of the
Lebesgue constant for Berrut's interpolation at equidistant nodes was proved
recently. A short review of this subject is presented. Some open problems are
suggested.
