A survey on difference hierarchies of regular languages [PDF]

open access: yesLogical Methods in Computer Science, 2018
Difference hierarchies were originally introduced by Hausdorff and they play an important role in descriptive set theory. In this survey paper, we study difference hierarchies of regular languages.

Descriptive Set Theory and Computable Topology (Dagstuhl Seminar 21461)

open access: yes, 2022
Computability and continuity are closely linked - in fact, continuity can be seen as computability relative to an arbitrary oracle. As such, concepts from topology and descriptive set theory feature heavily in the foundations of computable analysis ...

Descriptive set theory and harmonic analysis [PDF]

open access: yesJournal of Symbolic Logic, 1992
During the 1989 European ASL Summer Meeting in Berlin, the authors gave a series of eight lectures (short course) on the topic of the title. This survey article consists basically of the lecture notes for that course distributed to the participants of that conference. We have purposely tried in this printed version to preserve the informal style of the

The descriptive set-theoretic complexity of the set of points of continuity of a multi-valued function (Extended Abstract) [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
In this article we treat a notion of continuity for a multi-valued function F and we compute the descriptive set-theoretic complexity of the set of all x for which F is continuous at x.

Rate Distortion Theory for Descriptive Statistics

open access: yes, 2022
Rate distortion theory was developed for optimizing lossy compression of data, but it also has a lot of applications in statistics. In this paper we will see how rate distortion theory can be used to analyze a complicated data set involving orientations ...

An Application for Descriptive Nearness: Iris Recognition

open access: yesTopological Algebra and its Applications, 2017
Near Set Theory has various applications in the literature. In this paper, using the concept descriptive nearness, we show how to perform iris recognition. This process has a few algorithms given via Mathematica Script Language.

The descriptive set-theoretic complexity of the set of points of continuity of a multi-valued function [PDF]

open access: yesLogical Methods in Computer Science, 2011
In this article we treat a notion of continuity for a multi-valued function $F$ and we compute the descriptive set-theoretic complexity of the set of all $x$ for which $F$ is continuous at $x$.
