Computability in the Lattice of Equivalence Relations [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 We investigate computability in the lattice of equivalence relations on the natural numbers. We mostly investigate whether the subsets of appropriately defined subrecursive equivalence relations -for example the set of all polynomial-time decidable ...

A computational theory for the learning of equivalence relations [PDF]
Frontiers in Human Neuroscience, 2011 Equivalence relations are logical entities that emerge concurrently with the development of language capabilities.In this work we propose a computational model that learns to build equivalence relations by learning simple conditional rules.

A Neurocomputational Approach to Trained and Transitive Relations in Equivalence Classes
Frontiers in Psychology, 2017 A stimulus class can be composed of perceptually different but functionally equivalent stimuli. The relations between the stimuli that are grouped in a class can be learned or derived from other stimulus relations. If stimulus A is equivalent to B, and B

A further study on ordered regular equivalence relations in ordered semihypergroups
Open Mathematics, 2018 In this paper, we study the ordered regular equivalence relations on ordered semihypergroups in detail. To begin with, we introduce the concept of weak pseudoorders on an ordered semihypergroup, and investigate several related properties.

Some Equivalence Relations and Results over the Commutative Quaternions and Their Matrices
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 In this paper, we give some equivalence relations and results over the commutative quaternions and their matrices. In this sense, consimilarity, semisimilarity, and consemisimilarity over the commutative quaternion algebra and commutative quaternion ...

An Elementary Transition to Abstract Mathematics, 2019 • Definition: Let R be a binary relation on A. R is an equivalence relation on A if R is reflexive, symmetric, and transitive. • From the last section, we demonstrated that Equality on the Real Numbers and Congruence Modulo p on the Integers were ...

ON THE STRUCTURE OF COMPUTABLE REDUCIBILITY ON EQUIVALENCE RELATIONS OF NATURAL NUMBERS [PDF]
Journal of Symbolic Logic (JSL), 2021 We examine the degree structure $\operatorname {\mathrm {\mathbf {ER}}}$ of equivalence relations on $\omega $ under computable reducibility. We examine when pairs of degrees have a least upper bound.

Realizations of Countable Borel Equivalence Relations [PDF]
Memoirs of the American Mathematical Society, 2021 We study topological realizations of countable Borel equivalence relations, including realizations by continuous actions of countable groups, with additional desirable properties.

Equivalence relations and determinacy [PDF]
Journal of Mathematical Logic, 2022 We introduce the notion of [Formula: see text]-determinacy for [Formula: see text] a pointclass and [Formula: see text] an equivalence relation on a Polish space [Formula: see text]. A case of particular interest is the case when [Formula: see text] is the (left) shift-action of [Formula: see text] on [Formula: see text] where [Formula: see text] or ...
