On a fixed point in the metric space of normalized Hausdorff moment sequences

We show that the transformation (x_n)_{n\ge 1}\to (1/(1+x_1+...+x_n))_{n\ge 1} of the compact set of sequences (x_n)_{n\ge 1} of numbers from the unit interval [0,1] has a unique fixed point, which is attractive. The fixed point turns out to be a Hausdorff moment sequence studied in papers by Berg and Dur\'an in 2008.

New results and theorems on the vector-valued Markov moment problem are proved by means of polynomial approximation on unbounded subsets, also applying an extension of the positive linear operators’ result.

We show that the q-Digamma function ψq for 0<q<1 appears in an iteration studied by Berg and Durán. This is connected with the determination of the probability measure νq on the unit interval with…

We study the fixed point for a non-linear transformation in the set of Hausdorffmoment sequences,
defined by the formula: T ((an))n = 1/(a0+�E �E �E+an).We determine the corresponding measure�E,…
