It has been known that positive definiteness does not guarantee a bisequence to be a complex moment. However, it turns out that positive definite extendibility does (Theorems 1 and 22), and this is the main theme of this paper. The main tool is, generally understood, polar decomposition. To strength

An operator is called irreducible if it commutes with no nontrivial projection. Any rationally cyclic subnormal operator is unitarily equivalent to some S K, + , where K is a compact subset of C, + is a finite positive Borel measure article no.
We give an explicit solution to the scalar moment problem on semi-algebraic compact subsets of R n , and apply this result to the study of some operator multi-sequences.
For an indeterminate Stielijes moment sequence the multiplication operator \(M p(x)=x p(x)\) is positive definite and has self-adjoint extensions. Exactly one of these extensions has the same lower bound as \(M\). the so-called Friedrichs extension. The spectral measure of this extension gives a cer
