Pseudo MV-algebras and Lexicographic Product
We study algebraic conditions when a pseudo MV-algebra is an interval in the
lexicographic product of an Abelian unital -group and an -group
that is not necessary Abelian. We introduce -perfect pseudo MV-algebras
and strong -perfect pseudo MV-algebras, the latter ones will have a
representation by a lexicographic product. Fixing a unital -group
, the category of strong -perfect pseudo MV-algebras is
categorically equivalent to the category of -groups.Comment: arXiv admin note: text overlap with arXiv:1304.074
Lexicographic Effect Algebras
In the paper we investigate a class of effect algebras which can be
represented in the form of the lexicographic product \Gamma(H\lex G,(u,0)),
where is an Abelian unital po-group and is an Abelian directed
po-group. We study algebraic conditions when an effect algebra is of this form.
Fixing a unital po-group , the category of strong -perfect effect
algebra is introduced and it is shown that it is categorically equivalent to
the category of directed po-group with interpolation. We show some
representation theorems including a subdirect product representation by
antilattice lexicographic effect algebras
