R.Z. Dautov Sharp Estimates for the Polynomial Approximation in Weighted Sobolev Spaces/R.Z. Dautov, M.R. Timerbaev //Differential Equations, 2015, Vol. 51, No. 7, pp. 886–894 |
Аннотация |
We obtain sharp estimates for the accuracy of the best approximation of functions
by algebraic polynomials on an interval, the half-line, and the entire line in weighted Sobolev
spaces with Jacobi, Laguerre, and Hermite weights, respectively. We show that the orthogonal
polynomials associated with these weights form orthogonal bases in the respective weighted
Sobolev spaces. We obtain sharp estimates of Markov?Bernstein type |
