A. I. Fedotov Kazan (Volga Region) Federal University
Abstract:
Upper bounds for the norms of Hermite–Fejér interpolation operators in one-dimensional and multidimensional periodic Sobolev spaces are obtained. It is shown that, in the one-dimensional case, the norm of this operator is bounded. In the multidimensional case, the upper bound depends on the ratio of the numbers of nodes on separate coordinates.
Keywords:
