Generalization of blocks for \(D\)-lattices and lattice-ordered effect algebras. (English) Zbl 0968.81003
Summary: We show that every \(D\)-lattice (lattice-ordered effect algebra) \(P\) is a set-theoretic union of maximal subsets of mutually compatible elements, called blocks. Moreover, blocks are sub-\(D\)-lattices and sub-effect algebras of \(P\) which are \(MV\)-algebras closed with respect to all suprema and infima existing in \(P\).
