Special N-extremal solutions to indeterminate moment problems

Christian Berg, Ryszard Szwarc

For an N-extremal solution $μ$ to an indeterminate moment problem it is known by a theorem of M. Riesz that the measure $(1 + x^{2})^{- 1} d μ (x)$ is determinate. For $0 < α < 1$ we show by c…

Indeterminate Stieltjes moment problems revisited

Christian Berg

We consider a normalized indeterminate Hamburger moment sequence s which is supposed to be Stieltjes. We revisit old results about determinacy/indeterminacy in the sense of Stieltj…
