Dirichlet polynomials and a moment problem

چکیده
Consider a linear functional L defined on the space $${\mathcal {D}}[s]$$ of Dirichlet polynomials with real coefficients and set {D}}_+[s]$$ non-negative elements in {D}}[s].$$ An analogue Riesz–Haviland theorem this context asks: What are all -positive functionals L, which moment functionals? Since {D}}[s],$$ when considered as subspace $$C([0, \infty ), {\mathbb {R}}),$$ fails to be an adapted sense Choquet, general form is not applicable situation. In attempt answer forgoing question, we arrive at notion sequence, call Hausdorff log-moment sequence. Apart from theorem, show that any sequence combination $$\{1, 0, \ldots , \}$$ $$\{f(\log (n)\}_{n \geqslant 1}$$ for completely monotone function $$f : [0, ) \rightarrow ).$$ Moreover, such f uniquely determined by question.

Hyperbolic Polynomials and the Dirichlet Problem
This paper presents a simple, self-contained account of G̊arding’s theory of hyperbolic polynomials, including a recent convexity result of Bauschke-Guler-Lewis-Sendov and an inequality of Gurvits. This account also contains new results, such as the existence of a real analytic arrangement of the eigenvalue functions. In a second, independent part of the paper, the relationship of G̊arding’s theo...

متن کاملThe tracial moment problem and trace-optimization of polynomials
The main topic addressed in this paper is trace-optimization of polynomials in noncommuting (nc) variables: given an nc polynomial f , what is the smallest trace f(A) can attain for a tuple of matrices A? A relaxation using semidefinite programming (SDP) based on sums of hermitian squares and commutators is proposed. While this relaxation is not always exact, it gives effectively computable bou...
متن کاملSolution of the Dirichlet Problem by Interpolating Harmonic Polynomials
1. Introduction. Let Dbea bounded simply connected region of the complex z-plane which is regular for the Dirichlet problem, let C be the boundary of D, and let u be a continuous function on C to the real numbers. Some time ago J. L. Walsh [l, p. 517] suggested that it might be possible to define a sequence of harmonic polynomials by coincidence with the values of u in points so chosen on C tha...
