Balanced Operators and Operator Domains
Konrad Schmüdgen
We shall say that a densely defined closed operator on a Hilbert space is balanced if $\cD(T)=\cD(T^*)$. Balanced operators are described in terms of their phase operators abnd…
On the multidimensional K-moment problem
Konrad Schmüdgen
We prove a solvability theorem for the Stieltjes moment problem on which is based on the multivariate Stieltjes condition , $j=1…
Ten Lectures on the Moment Problem
Konrad Schmüdgen
These are ten lectures on the moment problem delivered by the author at the Vietnam Institute of Advanced Studies in Mathematics, Hanoi, March 2019. The first 3 lectures are about…
The multidimensional truncated Moment Problem: The Moment Cone
Philipp J. di Dio, Konrad Schmüdgen
Let , , be measurable functions on a measurable space . If is a positive measure on $(\mathcal{X},\mat…
On the infinite-dimensional moment problem
Konrad Schmüdgen
This paper deals with the moment problem on a (not necessarily finitely generated) commutative unital real algebra . We define moment functionals on as linear functionals wh…
Spectral theory of Schrödinger operators with infinitely many point interactions and radial positive definite functions
Mark M. Malamud, Konrad Schmüdgen
A number of results on radial positive definite functions on related to Schoenberg's integral representation theorem are obtained. They are applied to the study of…
