Effective algebras

1995
Abstract The theory of the computable functions establishes the scope and limits of computation by means of algorithms on the set N = (0,1,2,...) of natural numbers. It is based on the assumption that this set of data, equipped with some very simple operations, forms an algebraic structure that is computable in some absolute sense ...

Effect algebras and quantum MV algebras

2004
In Chapter 4 we have seen how the system of all effects in a Hilbert space gives rise to a “genuine” Brouwer Zadeh poset (which is neither an orthoposet nor a lattice). We will now study other interesting ways of structuring the set of all concrete effects.

Effect algebraic extensions of generalized effect algebras and two-valued states

Fuzzy Sets and Systems, 2008
The existence of a two-valued state on a lattice effect algebra is analyzed. Sufficient and necessary conditions for the existence of a such state are given in the following cases: (1) Archimedean atomic lattice effect algebras; (2) Archimedean atomic distributive lattice effect algebras; (3) (o)-continuous Archimedean atomic effect algebras. Moreover,
