Best Approximation and Moduli of Smoothness for Doubling Weights
Copyright policy )Best Approximation and Moduli of Smoothness for Doubling Weights
The authors relate the rate of weighted polynomial approximation to some weighted moduli of smoothness for so-called doubling weights. They also consider the problem in a more restrictive sense for generalized Jacobi weights with zeros in the interval of approximation. These zeros constitute a special problem that has not been resolved so far.
