Balanced identity in the minimal groups paradigm. [PDF]

open access: yesPLoS ONE, 2013
Balanced Identity Theory [1] formalizes a set of relationships between group attitude, group identification, and self-esteem. While these relationships have been demonstrated for familiar and highly salient social categories, questions remain regarding ...

Ideal topologies in higher descriptive set theory [PDF]

open access: yesAnnals of Pure and Applied Logic, 2022
We investigate generalizations of the topology of the higher Cantor space on $2^ $, based on arbitrary ideals rather than the bounded ideal on $ $. Our main focus is on the topology induced by the nonstationary ideal, and we call this topology the nonstationary topology, or also the Edinburgh topology on $2^ $. It may be of independent interest that

No Uncountable Polish Group Can be a Right-Angled Artin Group

open access: yesAxioms, 2017
We prove that if G is a Polish group and A a group admitting a system of generators whose associated length function satisfies: (i) if 0 < k < ω , then l g ( x ) ≤ l g ( x k ) ; (ii) if l g ( y ) < k < ω and x

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.

Classical descriptive set theory as a refinement of effective descriptive set theory

open access: yesAnnals 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.

Martin's conjecture, arithmetic equivalence, and countable Borel equivalence relations [PDF]

open access: yes, 2011
There is a fascinating interplay and overlap between recursion theory and descriptive set theory. A particularly beautiful source of such interaction has been Martin's conjecture on Turing invariant functions.

The Status of Normative Propositions in the Theory of Scientific Change

open access: yesScientonomy, 2016
The scope of the Theory of Scientific Change (TSC) encompasses any and all changes that occur in a given scientific mosaic, the set of all methods employed and theories accepted at a given time by a given scientific community.

A novel approach towards Heronian mean operators in multiple attribute decision making under the environment of bipolar complex fuzzy information

open access: yesAIMS Mathematics, 2023
One of the most effective and impressive approaches to tackle uncertainty is the theory of bipolar complex fuzzy set (BCFS). The theory of BCFS modified the theory of fuzzy set (FS), bipolar FS (BFS), and complex FS.
