Magnifiers in Some Generalization of the Full Transformation Semigroups

open access: yesMathematics, 2020
An element a of a semigroup S is called a left [right] magnifier if there exists a proper subset M of S such that a M = S ( M a = S ) .

On asymptotic statistical equivalence of order  of generalised difference sequences [PDF]

open access: yesMaejo International Journal of Science and Technology, 2014
We introduce and examine the concepts of asymptotic statistical equivalence of order  , and strong  asymptotic equivalence of order of sequences. Also, we give some relations connected to these concepts.

Measure reducibility of countable Borel equivalence relations [PDF]

open access: yes, 2017
We show that every basis for the countable Borel equivalence relations strictly above $\mathbb{E}_0$ under measure reducibility is uncountable, thereby ruling out natural generalizations of the Glimm-Effros dichotomy.

Computably Enumerable Equivalence Relations [PDF]

open access: yesStudia Logica, 2001
We study computably enumerable equivalence relations (ceers) on N and unravel a rich structural theory for a strong notion of reducibility among ceers.

Reorganization of equivalence classes: analysis of reversed baseline relations Reorganização de classes de equivalência: análise do número de relações de linha de base revertidas

open access: yesPsicologia: Reflexão e Crítica, 2011
The reorganization of equivalence classes may depend on the number of reversed baseline relations. To investigate this hypothesis, 28 undergraduate students distributed in four groups were exposed to a matching-to-sample procedure to establish ...

Exploring pre-service mathematics teachers’ intuitive strategies for solving open equivalence relations problems

open access: yesPythagoras
This article contributes to the body of research on equivalence relations by delineating the levels of sophistication and efficiency in the intuitive strategies employed by pre-service teachers (PSTs).

Hyper-u-amenability and Hyperfiniteness of Treeable Equivalence Relations

open access: yesForum of Mathematics, Sigma
We introduce the notions of u-amenability and hyper-u-amenability for countable Borel equivalence relations and we show that treeable, hyper-u-amenable countable Borel equivalence relations are hyperfinite.

Equivalence class formation in 11-month-old pre-linguistic infants

open access: yesActa Colombiana de Psicología
Several studies have attempted to assess the role of naming in the emergence of equivalence relations, but results are inconsistent; on the one hand, there are reports of equivalence emerging without naming and on the other hand, some authors claim that ...

DR/DZ equivalence conjecture and tautological relations [PDF]

open access: yesGeometry and Topology, 2017
In this paper we present a family of conjectural relations in the tautological ring of the moduli spaces of stable curves which implies the strong double ramification/Dubrovin-Zhang equivalence conjecture.
