Abstract

We give (necessary and sufficient) conditions on a sequence $\{ f_{n}\} _{n=0}^{\infty}$ of functions under which every generalized Stieltjes moment problem \[ \int_{0}^{\infty} f_{n}(x)\phi(x)\,{d} x=a_{n}, \ \quad n\in\mathbb{N}, \] has solutions $\phi\in\mathcal{S}(\mathbb{R})$ with $\operatorname{supp} \phi\subseteq[0,\infty)$. Furthermore, we consider more general problems of this kind for measure or distribution sequences $\{ f_{n}\} _{n=0}^{\infty}$. We also study vector moment problems with values in Fréchet spaces and multidimensional moment problems.
