Minimal conditions on Clifford semigroup congruences
International Journal of Mathematics and Mathematical Sciences, 2006 A known result in groups concerning the inheritance of minimal conditions on normal subgroups by subgroups with finite indexes is extended to semilattices of groups [E(S),Se,ϕe,f] with identities in which all ϕe,f are epimorphisms (called q partial ...

A note on operations of hesitant fuzzy sets [PDF]
International Journal of Computational Intelligence Systems, 2015 In this paper, properties of operations and algebraic structures of hesitant fuzzy sets are investigated. Semilattices of hesitant fuzzy sets with union and intersection are discussed, respectively.

Sequences suffice for pointfree uniform completions
Journal of the London Mathematical Society, Volume 112, Issue 2, August 2025.Abstract Completions of metric spaces are usually constructed using Cauchy sequences. However, this does not work for general uniform spaces, where Cauchy filters or nets must be used instead. The situation in pointfree topology is more straightforward: the correct completion of uniform locales can indeed be obtained as a quotient of a locale of Cauchy

On the Semantics and the Ontology of the Mass‐Count Distinction
Philosophy Compass, Volume 20, Issue 3, March 2025.ABSTRACT The mass‐count distinction is a morpho‐syntactic distinction among nouns in English and many other languages. Tree, chair, person, group, and portion are count nouns, which come with the plural and accept numerals such as one and first; water, rice, furniture, silverware, and law enforcement are mass nouns, which lack the plural and do not ...

Equational characterizations for some subclasses of domains
Open MathematicsIt is well known that the continuity of a poset can be seen as a special distributivity. There is an open problem: is there an equational characterization for continuous semilattices?

Representation of right zero semigroups and their semilattices by a transformation semigroup
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022 Background. As is known, an arbitrary semigroup can be represented by a semigroup of transformations that are right shifts either in this semigroup itself or in the extended semigroup obtained from the original one by adding an outer unit. The problems

Logic Journal of the IGPL, 2023 Abstract We devise exact conditions under which a join semilattice with a weak contact relation can be semilattice embedded into a Boolean algebra with an overlap contact relation, equivalently, into a distributive lattice with additive contact relation.

Truthmaker Semantics and Natural Language Semantics
Language and Linguistics Compass, Volume 19, Issue 1, January/February 2025.ABSTRACT Truthmaker semantics is a non‐classical logical framework that has recently garnered significant interest in philosophy, logic, and natural language semantics. It redefines the propositional connectives and gives rise to more fine‐grained entailment relations than classical logic.

Endomorphism monoids of semilattices of semigroups
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017 We prove that the endomorphism monoid of a semilattice of semigroups, which are semilattice indecomposable, is isomorphically embedded into the wreath product of a transformation semigroup with a small category.

Partial categorification of Hopf algebras and representation theory of towers of \mathcalJ-trivial monoids [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 This paper considers the representation theory of towers of algebras of $\mathcal{J} -trivial$ monoids. Using a very general lemma on induction, we derive a combinatorial description of the algebra and coalgebra structure on the Grothendieck rings $G_0 ...
