Orthomodular Lattices Induced by the Concurrency Relation [PDF]
We apply to locally finite partially ordered sets a construction which associates a complete lattice to a given poset; the elements of the lattice are the closed subsets of a closure operator, defined starting from the concurrency relation. We show that,

Residuated Structures and Orthomodular Lattices [PDF]
AbstractThe variety of (pointed) residuated lattices includes a vast proportion of the classes of algebras that are relevant for algebraic logic, e.g., $$\ell $$ ℓ -groups, Heyting algebras, MV-algebras, or De Morgan monoids.

Weakly Orthomodular and Dually Weakly Orthomodular Lattices [PDF]
The authors study the varieties of lattices with a unary operation~\('\) satisfying one or two or the following equations: \begin{align*} x= & (x\land y) \lor (x\land (x\land y)')\\ x= & (x\lor y) \land (x\lor (x\lor y)')\,. \end{align*} In ortholattices, any of these equations is equivalent to orthomodularity.

Orthomodular Lattices and Quantales [PDF]
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.

Conrad’s Partial Order on P.Q.-Baer *-Rings
We prove that a p.q.-Baer *-ring forms a pseudo lattice with Conrad’s partial order and also characterize p.q.-Baer *-rings which are lattices. The initial segments of a p.q.-Baer *-ring with the Conrad’s partial order are shown to be an orthomodular ...

A Note of Filters in Effect Algebras
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
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 ...

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 ...

A Comparison of Implications in Orthomodular Quantum Logic—Morphological Analysis of Quantum Logic
Morphological operators are generalized to lattices as adjunction pairs (Serra, 1984; Ronse, 1990; Heijmans and Ronse, 1990; Heijmans, 1994). In particular, morphology for set lattices is applied to analyze logics through Kripke semantics (Bloch, 2002; Fujio and Bloch, 2004; Fujio, 2006).

Commutators in Orthomodular Lattices
The author introduces the notions of a ''commutator'' for a possibly infinite set of elements M of an orthomodular lattice L and ''partial compatible'' (p.c.) for M with respect to some element \(a\in C(M)\) such that \(\{\) \(m\wedge a|\) \(m\in M\}\) is Boolean. If M is p.c. for \(a\in L\) then \(a\leq com(M)\) and CC(M) is p.c.
