Decomposition of $ℓ$ -group-valued measures

Giuseppina Barbieri, Antonietta Valente, Hans Weber (2012)

Czechoslovak Mathematical Journal

We deal with decomposition theorems for modular measures $μ : L \to G$ defined on a D-lattice with values in a Dedekind complete $ℓ$ -group. Using the celebrated band decomposition theorem of Riesz in Dedekind complete $ℓ$ -groups, several decomposition theorems including the Lebesgue decomposition theorem, the Hewitt-Yosida decomposition theorem and the Alexandroff decomposition theorem are derived. Our main result—also based on the band decomposition theorem of Riesz—is the Hammer-Sobczyk decomposition for $ℓ$ -group-valued...

Dimension in algebraic frames

Jorge Martinez (2006)

Czechoslovak Mathematical Journal

In an algebraic frame $L$ the dimension, $dim (L)$ , is defined, as in classical ideal theory, to be the maximum of the lengths $n$ of chains of primes $p_{0} < p_{1} < \dots < p_{n}$ , if such a maximum exists, and $\infty$ otherwise. A notion of “dominance” is then defined among the compact elements of $L$ , which affords one a primefree way to compute dimension. Various subordinate dimensions are considered on a number of frame quotients of $L$ , including the frames $d L$ and $z L$ of $d$ -elements and $z$ -elements, respectively. The more concrete illustrations...

Direct factors of multilattice groups. II.

Archivum Mathematicum

Subgroups of a directed distributive multilattice group $G$ are characterized which are direct factors of $G$ . The main result is formulated in Theorem 2.

Direct summands and retract mappings of generalized $M V$ -algebras

Ján Jakubík (2008)

Czechoslovak Mathematical Journal

In the present paper we deal with generalized $M V$ -algebras ( $G M V$ -algebras, in short) in the sense of Galatos and Tsinakis. According to a result of the mentioned authors, $G M V$ -algebras can be obtained by a truncation construction from lattice ordered groups. We investigate direct summands and retract mappings of $G M V$ -algebras. The relations between $G M V$ -algebras and lattice ordered groups are essential for this investigation.

Distinguished completion of a direct product of lattice ordered groups

Ján Jakubík (2001)

Czechoslovak Mathematical Journal

The distinguished completion $E (G)$ of a lattice ordered group $G$ was investigated by Ball [1], [2], [3]. An analogous notion for $M V$ -algebras was dealt with by the author [7]. In the present paper we prove that if a lattice ordered group $G$ is a direct product of lattice ordered groups $G_{i}$ $(i \in ...$

Divisibility in certain automorphism groups

Ramiro H. Lafuente-Rodríguez (2007)

Czechoslovak Mathematical Journal

We study solvability of equations of the form $x^{n} = g$ in the groups of order automorphisms of archimedean-complete totally ordered groups of rank 2. We determine exactly which automorphisms of the unique abelian such group have square roots, and we describe all automorphisms of the general ones.

Divisible effect algebras and interval effect algebras

Sylvia Pulmannová (2001)

Commentationes Mathematicae Universitatis Carolinae

It is shown that divisible effect algebras are in one-to-one correspondence with unit intervals in partially ordered rational vector spaces.
