Varieties whose tolerances are homomorphic images of their congruences [PDF]

, 2012
The homomorphic image of a congruence is always a tolerance (relation) but, within a given variety, a tolerance is not necessarily obtained this way. By a Maltsev-like condition, we characterize varieties whose tolerances are homomorphic images of their ...

The possible values of critical points between strongly congruence-proper varieties of algebras [PDF]

, 2014
We denote by Conc(A) the semilattice of all finitely generated congruences of an (universal) algebra A, and we define Conc(V) as the class of all isomorphic copies of all Conc(A), for A in V, for any variety V of algebras.

Dependent Space and Attribute Reduction on Fuzzy Information System

ITM Web of Conferences, 2017
From equivalence relation RBδ on discourse domain U, we can derive equivalence relation Rδ on the attribute set A. From equivalence relation Rδ on discourse domain A, we can derive a congruence relation on the attribute power set P(A) and establish an ...

Congruence relation in fuzzy partial hyperalgebras [PDF]

Journal of Hyperstructures
In this paper, we begin by introducing the concept of fuzzy partial hyperalgebra and exploring the relationships between congruence relations and strong congruence relations within this framework.

Mindset as Characteristic Adaptations: Using Response Surface Analysis to Assess Mindset in the Personality System

Frontiers in Psychology, 2021
This study aimed to assess the congruencies and discrepancies between mindset domains in relation to well-being and sought to demonstrate that mindset falls into the characteristic adaptation level of personality.

The Frenet Serret Description of Gyroscopic Precession [PDF]

, 1993
The phenomenon of gyroscopic precession is studied within the framework of Frenet-Serret formalism adapted to quasi-Killing trajectories. Its relation to the congruence vorticity is highlighted with particular reference to the irrotational congruence ...

Rough bipolar fuzzy ideals in semigroups

Complex & Intelligent Systems, 2023
Fuzzy set (FS) theory and rough sets (RSs) are constructed to accommodate the data uncertainty. In contrast, the bipolar FS (BFS) theory can tackle the uncertainty and the bipolarity of the data in different circumstances.

Sachs' free data in real connection variables [PDF]

, 2017
We discuss the Hamiltonian dynamics of general relativity with real connection variables on a null foliation, and use the Newman-Penrose formalism to shed light on the geometric meaning of the various constraints.

Relative annihilator-preserving congruence relations and relative annihilator-preserving homomorphisms in bounded distributive semilattices

Open Mathematics, 2014
In this paper we shall study a notion of relative annihilator-preserving congruence relation and relative annihilator-preserving homomorphism in the class of bounded distributive semilattices. We shall give a topological characterization of this class of

Vague Congruences and Quotient Lattice Implication Algebras

The Scientific World Journal, 2014
The aim of this paper is to further develop the congruence theory on lattice implication algebras. Firstly, we introduce the notions of vague similarity relations based on vague relations and vague congruence relations.
