Solution of the Stieltjes Truncated Moment Problem
The conditions of solvability and description of all solutions of the truncated Stieltjes moment problem are obtained using as the starting point earlier results on the Hamburger truncated moment problem. An algebraic algorithm for the explicit solution of both problems is proposed.
متن کاملTwo Sandwich Theorems for Linear Operators and the Moment Problem
We give a direct proof for theorem 2 [13] (which is equivalent to theorem 1 [15]). Then we apply theorems 1 [15] and 4 [15] to some concrete spaces of sequences or functions which have a Schauder basis. The polynomials xj(t) = t j , j ∈ N considered in the classical moment problem, are replaced by the elements of the Schauder basis. Mathematics Subject Classification: 46A22, 47A57.
متن کاملThe K-moment Problem for Continuous Linear Functionals
Given a closed (and non necessarily compact) basic semialgebraic set K ⊆ R, we solve the K-moment problem for continuous linear functionals. Namely, we introduce a weighted l1-norm lw on R[x], and show that the lw-closures of the preordering P and quadratic module Q (associated with the generators of K) is the cone Psd(K) of polynomials nonnegative on K. We also prove that P and Q solve the K-m...
متن کاملSome properties of continuous linear operators in topological vector PN-spaces
The notion of a probabilistic metric space corresponds to thesituations when we do not know exactly the distance. Probabilistic Metric space was introduced by Karl Menger. Alsina, Schweizer and Sklar gave a general definition of probabilistic normed space based on the definition of Menger [1]. In this note we study the PN spaces which are topological vector spaces and the open mapping an...
متن کاملStieltjes moment problem via fractional moments
Stieltjes moment problem is considered to recover a probability density function from the knowledge of its infinite sequence of ordinary moments. The approximate density is obtained through maximum entropy technique, under the constraint of few fractional moments. The latter are numerically obtained from the infinite sequence of ordinary moments and are chosen in such a way as to convey the max...
