Determinacy of a Rational Moment Problem

Truncated Moment Problem versus Moment Problem 3

It is shown that the truncated multidimensional moment problem is more general than the full multidimensional moment problem.

Relational Quantum Mechanics and the Determinacy Problem∗

Quantum mechanics describes certain systems as being in superpositions of their properties, yet every measurement on every system that we are able to perform yields a determinate result. The “orthodox” formulation of the theory builds this in by including a postulate that such superpositions “collapse” at the time of measurement. This strategy fails to really explain why such measurements are d...

Natural solutions of rational Stieltjes moment problems

In the strong or two-point Stieltjes moment problem, one has to find a positive measure on [0,∞) for which infinitely many moments are prescribed at the origin and at infinity. Here we consider a multipoint version in which the origin and the point at infinity are replaced by sequences of points that may or may not coincide. In the indeterminate case, two natural solutions μ0 and μ∞ exist that ...
