QUASIORDER LATTICES ARE FIVE-GENERATED
Journal Title: Discussiones Mathematicae - General Algebra and Applications - Year 2016, Vol 36, Issue 1
Abstract
transitive relation. The quasiorders on a set A form a complete lattice with respect to set inclusion. Assume that A is a set such that there is no inaccessible cardinal less than or equal to |A|; note that in Kuratowski’s model of ZFC, all sets A satisfy this assumption. Generalizing the 1996 result of Ivan Chajda and G´abor Cz´edli, also Tam´as Dolgos’ recent achievement, we prove that in this case the lattice of quasiorders on A is five-generated, as a complete lattice.

INTRODUCING FULLY UP-SEMIGROUPS
In this paper, we introduce some new classes of algebras related to UPalgebras and semigroups, called a left UP-semigroup, a right UP-semigroup, a fully UP-semigroup, a left-left UP-semigroup, a right-left UP-semigroup,...
NONDISTRIBUTIVE RINGS AND THEIR ORE ¨ LOCALIZATIONS
In the paper, we introduce the notion of a nondistributive ring N as a generalization of the notion of an associative ring with unit, in which the addition needs not be abelian and the distributive law is replaced by n0...
ON 2-ABSORBING FILTERS OF LATTICES
Let L be a lattice with 1. In this paper we study the concept of 2-absorbing filter which is a generalization of prime filter. A proper filter F of L is called a 2-absorbing filter (resp. a weakly 2-absorbing) if wheneve...
ON THE SUBSEMIGROUP GENERATED BY ORDERED IDEMPOTENTS OF A REGULAR SEMIGROUP
An element e of an ordered semigroup S is called an ordered idempotent if e ≤ e^2. Here we characterize the subsemigroup < E≤(S) > generated by the set of all ordered idempotents of a regular ordered semigroup S. If S is...
M-SOLID GENERALIZED NON-DETERMINISTIC VARIETIES
A generalized non-deterministic hypersubstitution is a mapping which maps operation symbols of type τ to the set of terms of the same type which does not necessarily preserve the arity. We apply the generalized nondeterm...
