DESCRIPTION:Approximating a function with rational interpolation often\ngives excellent results, but it is generally hard to control\nthe occurrence of poles. However, the particular class of\nbarycentric rational interpolants is guaranteed to have no\npoles and arbitrarily high approximation power. We first\ngive an introduction to this kind of interpolation and then\nstudy the corresponding Lebesgue constants, which turn out\nto have logarithmic growth in the case of equidistant\ninterpolation points.<br />\n[Invited by J-P.Berrut]
