A sharp error estimate of the best approximation by algebraic polynomials in the weighted space L2(-1, 1)

Dautov R. (2013)

We obtain an exact error estimate of the best approximation by algebraic polynomials in the Lebesgue space L2 (-1, 1) with the weight 1 - x2 of degreeλ > -1. © Allerton Press, Inc., 2013.
Estimate of the norm of the Lagrange interpolation operator in a multidimensional Sobolev space

Fedotov A. (2007)

We obtain an estimate of the norm of the Lagrange interpolation operator in a multidimensional Sobolev space. It is shown that, under a suitable choice of the sequence of multi-indices, interpolation polynomials converge ...
