Quasi-Polish spaces [PDF]

open access: yesAnnals of Pure and Applied Logic, 2013
We investigate some basic descriptive set theory for countably based completely quasi-metrizable topological spaces, which we refer to as quasi-Polish spaces. These spaces naturally generalize much of the classical descriptive set theory of Polish spaces to the non-Hausdorff setting.

Weak∗-Polish Banach spaces [PDF]

open access: yesJournal of Functional Analysis, 1988
If Y is a Banach space and a separable Banach space \(X\subset Y\) *, then X is said to be w *-Polish if the closed unit ball of X is Polish in the w *-topology (i.e. homeomorphic to a separable complete metric space). This property of Banach spaces is carefully studied in connection to properties like the point of continuity property, skipped blocking

Determining Ionospheric Drift and Anisotropy of Irregularities from LOFAR Core Measurements: Testing Hypotheses behind Estimation

open access: yesRemote Sensing, 2022
We try to assess the validity of assumptions taken when deriving drift velocity. We give simple formulas for characteristics of the spatiotemporal correlation function of the observed diffraction pattern for the frozen flow and the more general Briggs ...
