The support of the orthogonality measure of so-called little q-Laguerre polynomials {ln(.; a|q)}n=0∞, 0 < q < 1, 0 < a < q-1, is given by Sq = {1, q, q2,...} ∪ {0}. Based on a method of Mlotkowski and Szwarc we deduce a parameter set which admits

In this article, we study the sampling recovery problem for certain relevant multivariate function classes on the cube [0, 1]d, which are not compactly embedded into L∞([0,1]d). Recent tools relating the sampling widths to the Kolmogorov or best m-

Let S subset of R be compact with #S = infinity and let C(S) be the set of all real continuous functions on S. We ask for an algebraic polynomial sequence (P-n)(n=0)(infinity) with deg P-n = n such that every f is an element of C(S) has a unique repr

Background. We investigate the relationship between the boundedness of Lebesgue constants for the Lagrange polynomial interpolation on a compact subset of \[\mathbb R\] and the existence of a Faber basis in the space of continuous functions on this

We investigate some conditions under which the Lebesgue constants or Lebesgue functions are bounded for the classical Lagrange polynomial interpolation on a compact subset of $\mathbb R$. In particular, relationships of such boundedness with uniform
