Equationally Extremal Semilattices [PDF]
Journal of Siberian Federal University. Mathematics & Physics, 2017 In the current paper we study extremal semilattices with respect to their equational properties. In the class $\mathbf{S}_n$ of all semilattices of order $n$ we find semilattices which have maximal (minimal) number of consistent equations. Moreover, we find a semilattice in $\mathbf{S}_n$ with maximal sum of numbers of solutions of equations.

Semilattices of archimedean ordered semigroups [PDF]
, 2008 In this paper we deal with the decomposition of some classes of ordered semigroups into archimedean components. In particular, we prove that in ordered semigroups the concepts of semilattices of archimedean semigroups and of complete semilattices of ...

A Study of Ordered Ag-Groupoids in terms of Semilattices via Smallest (Fuzzy) Ideals
Advances in Fuzzy Systems, 2018 An ordered AG-groupoid can be referred to as an ordered left almost semigroup, as the main difference between an ordered semigroup and an ordered AG-groupoid is the switching of an associative law.

Small semilattices and costability [PDF]
, 1971 This dissertation centers its attention firstly on topological semilattices with small semi lattices and some equivalences of that property. This property is highly related to finite dimensional locally connected compact topological semi lattices and the

Semilattices with a congruence [PDF]
A specialization semilattice is a semilattice together with a coarser preorder satisfying a compatibility condition. We show that the category of specialization semilattices is isomorphic to the category of semilattices with a congruence, hence ...

Introducing Boolean Semilattices [PDF]
, 2018 We present and discuss a variety of Boolean algebras with operators that is closely related to the variety generated by all complex algebras of semilattices.

Ivanova contact join-semilattices are not finitely axiomatizable [PDF]
We show that the class of contact join-semilattices introduced by Ivanova (Contact join-semilattices. Stud Log 2022;110:1219-41) is not finitely axiomatizable.

Semilattices and indecomposable elements [PDF]
This thesis concerns the theory of semilattices, which are non-trivial discrete additive submonoids of Rn , which are contained in a cone. Special emphasis is on their indecomposable elements.
