1. Compatibility and central elements in pseudo-effect algebras Creator: Vitolo, Paolo Format: bez média and svazek Type: model:article and TEXT Subject: pseudo-effect algebra, lattice-pseudo--effect algebra, pseudo-MV-algebra, compatible elements, and central element Language: English Description: An equivalent definition of compatibility in pseudo-effect algebras is given, and its relationships with central elements are investigated.
