On the properties of spectral effect algebras [PDF]

open access: yesQuantum, 2019
The aim of this paper is to show that there can be either only one or uncountably many contexts in any spectral effect algebra, answering a question posed in [S. Gudder, Convex and Sequential Effect Algebras, (2018), arXiv:1802.01265].

Sequent Calculus Representations for Quantum Circuits [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2016
When considering a sequent-style proof system for quantum programs, there are certain elements of quantum mechanics that we may wish to capture, such as phase, dynamics of unitary transformations, and measurement probabilities. Traditional quantum logics

A Topological Study of Contextuality and Modality in Quantum Mechanics [PDF]

open access: yes, 2006
Kochen-Specker theorem rules out the non-contextual assignment of values to physical magnitudes. Here we enrich the usual orthomodular structure of quantum mechanical propositions with modal operators.

Matrices over orthomodular lattices [PDF]

open access: bronzeGlasgow Mathematical Journal, 1969
In this paper elementary properties are established for matrices whose coordinates are elements of a lattice L. In particular, many of the results of Luce [4] are extended to the case where L is an orthomodular lattice, a lattice with an orthocomplementation denoted by in which a ≦ b ⇒ a ∨(a′ ∧ b) = b.

Kadison’s antilattice theorem for a synaptic algebra

open access: yesDemonstratio Mathematica, 2018
We prove that if A is a synaptic algebra and the orthomodular lattice P of projections in A is complete, then A is a factor if and only if A is an antilattice.We also generalize several other results of R.

Orthomodular Lattices and Quantales [PDF]

open access: yesInternational Journal of Theoretical Physics, 2005
Let $L$ be a complete orthomodular lattice. There is a one to one correspondence between complete boolean subalgebras of $L$ contained in the center of $L$ and endomorphisms $j$ of $L$ satisfying the Borceux-Van den Bossche conditions.

A priori Knowledge and the Kochen-Specker Theorem [PDF]

open access: yes, 2006
We introduce and formalize a notion of "a priori knowledge" about a quantum system, and show some properties about this form of knowledge. Finally, we show that the Kochen-Specker theorem follows directly from this study. This version is a draft version,

A Note of Filters in Effect Algebras

open access: yesChinese Journal of Mathematics, Volume 2013, Issue 1, 2013., 2013
We investigate relations of the two classes of filters in effect algebras (resp., MV‐algebras). We prove that a lattice filter in a lattice ordered effect algebra (resp., MV‐algebra) E does not need to be an effect algebra filter (resp., MV‐filter). In general, in MV‐algebras, every MV‐filter is also a lattice filter.

On Intuitionistic Fuzzy Context‐Free Languages

open access: yesJournal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013
Taking intuitionistic fuzzy sets as the structures of truth values, we propose the notions of intuitionistic fuzzy context‐free grammars (IFCFGs, for short) and pushdown automata with final states (IFPDAs). Then we investigate algebraic characterization of intuitionistic fuzzy recognizable languages including decomposition form and representation ...

Conditional Probability, Three‐Slit Experiments, and the Jordan Algebra Structure of Quantum Mechanics

open access: yesAdvances in Mathematical Physics, Volume 2012, Issue 1, 2012., 2012
Most quantum logics do not allow for a reasonable calculus of conditional probability. However, those ones which do so provide a very general and rich mathematical structure, including classical probabilities, quantum mechanics, and Jordan algebras. This structure exhibits some similarities with Alfsen and Shultz′s noncommutative spectral theory, but ...
