Pseudoeffect algebras. II: Group representations. (English) Zbl 0994.81009
For the notation and terminology, see the review of Part I [ibid. 40, No. 3, 685–701 (2001; Zbl 0994.81008)].
The main result of the second part of the paper is the representation theorem which states that every pe.a. having RDP$$_1$$ is an interval pe.a. Furthermore, the categories of pe.a.s and of unital po-groups, both having RDP$$_1$$, are shown to be equivalent. It is also demonstrated that pseudo-MV algebras (introduced by G. Georgescu and A. Iorgulescu in a forthcoming paper) are pe.a.s with an additional structure.
