Models of Cohen measurability
We show that in contrast with the Cohen version of Solovay’s model, it is consistent for the continuum to be Cohen-measurable and for every function to be continuous on a non-meagre set.
متن کاملModels of real-valued measurability
Solovay's random-real forcing ([1]) is the standard way of producing real-valued measurable cardinals. Following questions of Fremlin, by giving a new construction, we show that there are combinatorial, measure-theoretic properties of Solovay's model that do not follow from the existence of real-valued measurability.
متن کاملMeasurability Properties of Spectra
We study Borel measurability of the spectrum in topological algebras. We give some equivalences of the various properties, show that the spectrum in a Banach algebra is continuous on a dense Gs, and prove that in a Polish algebra the set of invertible elements is an FaS and the inverse mapping is a Borel function of the second class. This article has its origin in the papers [7] and [5]. We stu...
متن کاملMeasurability and Computability
The conceptual relation between the measurability of quantum mechanical observables and the computability of numerical functions is re-examined. A new formulation is given for the notion of measurability with finite precision in order to reconcile the conflict alleged by M. A. Nielsen [Phys. Rev. Lett. 79, 2915 (1997)] that the measurability of a certain observable contradicts the Church-Turing...
متن کاملOn the Measurability of Triangles
Let ẽ ≥ φ be arbitrary. A central problem in arithmetic Lie theory is the computation of symmetric arrows. We show that ū ≡ ∞. In contrast, this reduces the results of [33] to an approximation argument. Therefore it is essential to consider that may be smooth.
