Relation between Exponential Moment Problem and Classical Moment Problem [PDF]

open access: yesProceedings of the Bulgarian Academy of Sciences
The main result of the paper is an interesting relation between the solution of the truncated exponential moment problem and truncated classical moment problem, considered on the half-line or on a compact interval.

Interactive effects of joint angle, contraction state and method on estimates of achilles tendon moment arms [PDF]

open access: yes, 2013
Copyright @ 2013 Human Kinetics, IncThe muscle-tendon moment arm is an important input parameter for musculoskeletal models. Moment arms change as a function of joint angle and contraction state and depend on the method being employed.

Continued fractions which correspond to two series expansions and the strong Hamburger moment problem [PDF]

open access: yes, 2012
Just as the denominator polynomials of a J-fraction are orthogonal polynomials with respect to some moment functional, the denominator polynomials of an M-fraction are shown to satisfy a skew orthogonality relation with respect to a stronger moment ...

The truncated matrix trigonometric moment problem with an open gap

open access: yesConcrete Operators, 2014
This paper is a continuation of our previous investigations on the truncated matrix trigonometric moment problem in Ukrainian Math. J., 2011, 63, no. 6, 786-797, and Ukrainian Math. J., 2013, 64, no. 8, 1199- 1214.

The Hausdorff Moment Problem [PDF]

open access: yesCanadian Mathematical Bulletin, 1978
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.

On bounded complex Jacobi matrices and related moment problems in the complex plane [PDF]

open access: yesSurveys in Mathematics and its Applications, 2023
In this paper we consider the following moment problem: find a positive Borel measure μ on ℂ subject to conditions ∫ zn dμ = sn, n∈ℤ+, where sn are prescribed complex numbers (moments).

Gravity as an ensemble and the moment problem

open access: yesJournal of High Energy Physics, 2021
If a bulk gravitational path integral can be identified with an average of partition functions over an ensemble of boundary quantum theories, then a corresponding moment problem can be solved. We review existence and uniqueness criteria for the Stieltjes

The Phase Transition Analysis for Random Regular Exact (s, c, k)—SAT Problem

open access: yesIEEE Access, 2021
The length of each clause in a regular $(s, c, k)-CNF$ formula is $k$ . Each argument occurrences $s$ times, among them, positive occurrences $(c * s)$ times and negative occurrences $(s-c*s)$ times, where $0 < c < 1$ . A regular exact $(

On unbounded commuting Jacobi operators and some related issues

open access: yesConcrete Operators, 2019
We consider the situations, when two unbounded operators generated by infinite Jacobi matrices, are self-adjoint and commute. It is found that if two Jacobi matrices formally commute, then two corresponding operators are either self-adjoint and commute ...

A Maximum Entropy Approach to the Realizability of Spin Correlation Matrices

open access: yesEntropy, 2013
Deriving the form of the optimal solution of a maximum entropy problem, we obtain an infinite family of linear inequalities characterizing the polytope of spin correlation matrices.
