New Directions in Descriptive Set Theory [PDF]
Bulletin of Symbolic Logic, 1999 §1. I will start with a quick definition of descriptive set theory: It is the study of the structure of definable sets and functions in separable completely metrizable spaces. Such spaces are usually calledPolish spaces. Typical examples are ℝn, ℂn, (separable) Hilbert space and more generally all separable Banach spaces, theCantor space2ℕ, theBaire ...

Generalized Descriptive Set Theory and Classification Theory [PDF]
Memoirs of the American Mathematical Society, 2010 Descriptive set theory is mainly concerned with studying subsets of the space of all countable binary sequences. In this paper we study the generalization where countable is replaced by uncountable. We explore properties of generalized Baire and Cantor spaces, equivalence relations and their Borel reducibility.

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

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

Borel Chain Conditions of Borel Posets
Mathematics, 2023 We study the coarse classification of partial orderings using chain conditions in the context of descriptive combinatorics. We show that (unlike the Borel counterpart of many other combinatorial notions), we have a strict hierarchy of different chain ...

The Embodiment of Corporate Social Responsibility in Sharia Enterprise Theory
Journal of Islamic Economic Laws, 2023 The issue of disclosure of social responsibility by entities is a theme that has always been debated. This is none other than because the implementation of social responsibility disclosures carried out by companies to date still shows a real impact.

Agency in Structure: An Inquiry into Gideon Toury’s Target-Oriented Perspective
transLogos: Translation Studies Journal, 2022 The present paper aims to present a rereading of Gideon Toury’s formulation of the target-oriented theory in his seminal work Descriptive Translation Studies — and Beyond in the hope of making a contribution to the discussion on Toury’s emphasis on ...

Real Analytic Machines and Degrees [PDF]
Logical Methods in Computer Science, 2011 We study and compare in two degree-theoretic ways (iterated Halting oracles analogous to Kleene's arithmetical hierarchy and the Borel hierarchy of descriptive set theory) the capabilities and limitations of three models of analytic computation: BSS ...
