Weak Boolean products of bounded dually residuated l -monoids

Jan Kühr, Jiří Rachůnek (2007)

Mathematica Bohemica

In the paper we deal with weak Boolean products of bounded dually residuated -monoids (DR l -monoids). Since bounded DRl-monoids are a generalization of pseudo MV-algebras and pseudo BL-algebras, the results can be immediately applied to these algebras.

Weak homogeneity of lattice ordered groups

Ján Jakubík (2007)

Czechoslovak Mathematical Journal

In this paper we deal with weakly homogeneous direct factors of lattice ordered groups. The main result concerns the case when the lattice ordered groups under consideration are archimedean, projectable and conditionally orthogonally complete.

When is every order ideal a ring ideal?

Melvin Henriksen, Suzanne Larson, Frank A. Smith (1991)

Commentationes Mathematicae Universitatis Carolinae

A lattice-ordered ring is called an OIRI-ring if each of its order ideals is a ring ideal. Generalizing earlier work of Basly and Triki, OIRI-rings are characterized as those f -rings such that / 𝕀 is contained in an f -ring with an identity element that is a strong order unit for some nil l -ideal 𝕀 of . In particular, if P ( ) denotes the set of nilpotent elements of the f -ring , then is an OIRI-ring if and only if / P ( ) is contained in an f -ring with an identity element that is a strong order unit....

When Min ( G ) - 1 has a clopen π -base

Ramiro Lafuente-Rodriguez, Warren Wm. McGovern (2021)

Mathematica Bohemica

It is our aim to contribute to the flourishing collection of knowledge centered on the space of minimal prime subgroups of a given lattice-ordered group. Specifically, we are interested in the inverse topology. In general, this space is compact and T 1 , but need not be Hausdorff. In 2006, W. Wm. McGovern showed that this space is a boolean space (i.e. a compact zero-dimensional and Hausdorff space) if and only if the l -group in question is weakly complemented. A slightly weaker topological property...
