MathematicsThe following two consequences of the axiom of constructibility V=L will be established for every n≥3: 1. Every linear Σn1 set is the projection of a uniform planar Πn−11 set. 2.

Classical descriptive set theory as a refinement of effective descriptive set theory
Annals of Pure and Applied Logic, 2010 Abstract The (effective) Suslin–Kleene Theorem is obtained as a corollary of a standard proof of the classical Suslin Theorem, by noticing that it is mostly constructive and applying to it a naive realizability interpretation.

The descriptive set theory of the Lebesgue Density Theorem [PDF]
Advances in Mathematics, 2013 Given an equivalence class $[A]$ in the measure algebra of the Cantor space, let $\hat ([A])$ be the set of points having density 1 in $A$. Sets of the form $\hat ([A])$ are called $\mathcal{T}$-regular. We establish several results about $\mathcal{T}$-regular sets. Among these, we show that $\mathcal{T}$-regular sets can have any complexity within $

Omitting types: application to descriptive set theory [PDF]
Proceedings of the American Mathematical Society, 1975 The omitting types theorem of infinitary logic is used to prove that every small Π 1 1 \Pi _1^1 set of analysis or any small Σ 1 {\Sigma _1} set of set theory is constructible.

Generalized Descriptive Set Theory and Classification Theory [PDF]
, 2020 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.

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.

A comparison of concepts from computable analysis and effective descriptive set theory [PDF]
Mathematical Structures in Computer Science, 2014 Computable analysis and effective descriptive set theory are both concerned with complete metric spaces, functions between them and subsets thereof in an effective setting.

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 ...
