Hausdorff moment problem and fractional moments
Applied Mathematics and Computation, 2010In probabilistic terms, the Hausdorff moment problem means to recover an unknown probability density function \(f\in L^2[0,1]\) from the knowledge of its associated sequence \(\{\mu_j\}^M_{j=0}\) of integer moments, that is, \(\mu_j=\int_0^1x^jf(x),j\geq0,\mu_0=1\). The authors propose a solution to the Hausdorff moment problem using fractional moments,

Theq-Laguerre Polynomials and Related Moment Problems
Journal of Mathematical Analysis and Applications, 1998 We study two indeterminate Hamburger moment problems associated withq-Laguerre polynomials. The coefficients in their recurrence relations are of exponential growth. This completes earlier work started by D. Moak.

Noncommutative moments problem
Functional Analysis and Its Applications, 1987Let \(U\) be a unitary representation of a real finite-dimensional Lie group \(G\) on a separable complex Hilbert space \(H\) and let \(dU\) be the corresponding representation of the complex enveloping *-algebra \(L\) of \(G\), defined on a domain \(D\subseteq H\).

Canadian Mathematical Bulletin, 1981
We shall apply the spectral theorem for self adjoint operators in Hilbert space to study an operator version of the Stieltjes moment problem [1]. In the course of the work we shall make use of the Friedrichs extension theorem which states that any non-negative symmetric operator in Hilbert space has a non-negative self adjoint extension.

In {\S} 2 of this paper, the author fixes the objects of his investigation and states simple results. Further the paper contains a suitable description and properties of sets of solutions as well as relations between different kinds of moment problems.

The quantum problem of moments II
Reports on Mathematical Physics, 1970Positive definite functional on the algebra A generated by the position and momentum operators are investigated. The necessary and sufficient condition for the existence of a density matrix representing a given positive definite functional ω is formulated.
