Regular omega-Languages with an Informative Right Congruence [PDF]
A regular language is almost fully characterized by its right congruence relation. Indeed, a regular language can always be recognized by a DFA isomorphic to the automaton corresponding to its right congruence, henceforth the Rightcon automaton. The same

Congruence relation in fuzzy partial hyperalgebras [PDF]
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.

Dependent Space and Attribute Reduction on Fuzzy Information System
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 ...

On n-ary ring congruences of n-ary semirings
In universal algebra, it is well-known that if S is an algebraic structure, then the kind of algebraic structure of S/ρ is similar to S where ρ is a congruence relation on S.

Endomorphism kernel property for finite groups [PDF]
A group $G$ has the endomorphism kernel property (EKP) if every congruence relation $\theta$ on $G$ is the kernel of an endomorphism on $G$. In this note we show that all finite abelian groups have EKP and we show infinite series of finite non-abelian ...

Some subvarieties of semiring variety COS$ ^{+}_{3} $
In this paper, we study some subvarieties of a semiring variety determined by certain additional identities. We first present alternative characterizations for equivalences $ \overset{+}{\mathcal{H}}{\cap}\overset{\cdot}{\mathcal{L}} $, $ \overset ...

Relations among Ramanujan-type congruences I
We show that Ramanujan-type congruences are preserved by the action of the shallow Hecke algebra and provide several structure results for them. We discover a dichotomy between congruences originating in Hecke eigenvalues and congruences on arithmetic progressions with cube-free periods. The scarcity of the latter was investigated recently.

Rough bipolar fuzzy ideals in semigroups
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.

Vague Congruences and Quotient Lattice Implication Algebras
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.
