Transformations of Moment Functionals
Philipp J. di Dio
In measure theory several results are known how measure spaces are transformed into each other. But since moment functionals are represented by a measure we investigate in this stu…

The multidimensional truncated Moment Problem: Shape and Gaussian Mixture Reconstruction from Derivatives of Moments
Philipp J. di Dio
In this paper we introduce the theory of derivatives of moments and (moment) functionals to represent moment functionals by Gaussian mixtures, characteristic functions of polytopes…

Weyl Circles for one-dimensional Moment Problems
Philipp di Dio
In the present paper we calculate the centers and radii of Weyl circles from the Nevanlinna parametrization for various one-dimensional moment problems (Hamburger moment problem, S…
