Approximation with exponential weights in (−1, 1)

Abstract We construct Shepard-type operators for weighted uniform approximation of functions with endpoint singularities by exponential-type weights in [−1,1]. Convergence theorems and pointwise and uniform approximation error estimates not possible by polynomials are proved.
