Moment Problems in Hereditary Function Spaces
We introduce a concept of hereditary set of multi-indices, and consider vector spaces of functions generated by families associated to such sets of multi-indices, called hereditary function spaces.

Integral representations for harmonic and biharmonic functions in the unit ball (in Russian) [PDF]
In the paper an analytical solution of the analytic continuation problem in the unit N-dimensional ball by its values on the inner sphere is found. A generalization of the classical Poisson formula is obtained.

The insight phenomenon is thought to comprise two components: cognitive and affective (the Aha! experience). The exact nature of the Aha! experience remains unclear; however, several explanations have been put forward.

From asymptotics to spectral measures: determinate versus indeterminate moment problems [PDF]
In the field of orthogonal polynomials theory, the classical Markov theorem shows that for determinate moment problems the spectral measure is under control of the polynomials asymptotics.

The authors consider the quartic moment problem suggested by \textit{R. E. Curto} and \textit{L. A. Fialkow} in [Mem. Am. Math. Soc. 568, 52 p. (1996; Zbl 0876.30033)]. Given complex numbers \(\gamma\equiv\gamma^{(4)}:\gamma_{00}, \gamma_{01}, \gamma_{10}, \gamma_{02}, \gamma_{11}, \gamma_{20}, \gamma_{03}, \gamma_{12}, \gamma_{21}, \gamma_{30 ...

The Hausdorff Moment Problem [PDF]
Suppose throughout thatand that {μn}(n≥ 0) is a sequence of real numbers. The (generalized) Hausdorff moment problem is to determine necessary and sufficient conditions for there to be a function x in some specified class satisfying.

Metric of a Slow Rotating Body with Quadrupole Moment from the Erez-Rosen Metric [PDF]
A metric representing a slowly rotating object with quadrupole moment is obtained using a perturbation method to include rotation into the weak limit of the Erez-Rosen metric.

A Family of Heat Functions as Solutions of Indeterminate Moment Problems
We construct a family of functions satisfying the heat equation and show how they can be used to generate solutions to indeterminate moment problems. The following cases are considered: log-normal, generalized Stieltjes-Wigert, and q-Laguerre.

Moment problems for operator polynomials
We extend Haviland's theorem on the integral representation of positive linear functionals on usual (real multivariate) polynomials to the integral representation of positive linear maps on operator polynomials mapping into the space of operators.
