Test groups and effect algebras
The notion of a test group as a pair \((G, T)\), where \(G\) is a partially ordered Abelian group and \(T\) is a generative antichain in its positive cone, is introduced. This notion is connected with representation of effect algebras and it has an intimate connection with D-test spaces introduced by the reviewer and \textit{S. Pulmannová} [Rep. Math. Phys. 34, 151-170 (1994; Zbl 0820.03038)]. In addition, some methods to calculate the algebraic closure, and some ideas about quotient effect algebras are presented.
