Weighted Approximation by Rational Operators

Results in Mathematics, 2003
In this interesting paper, the author considers Shephard-type rational operators \[ S_n(f; x)= \Biggl[\sum^{n-1}_{k=1}| x- x_k|^{-s} f(x_k)\Biggr]\Biggl/\Biggl[\sum^{n-1}_{k=1}| x- x_k|^{-s}\Biggr] \] for appropriately chosen nodes \(\{x_k\}\) in \([-1,1]\). Let \(\alpha> 0\) and \[ w(x)= (1- x^2)^\alpha,\quad x\in [-1,1]. \] The author establishes the
