The Logic of Partitions and Partition Logics: Ore's Correspondence, Contextual Pasting, and Direct-Sum Decompositions
Karl Svozil
The term ``partition logic'' denotes two constructions at different levels. In automaton and generalized-urn models, selected partitions generate Boolean event algebras whose conte…
Which Classicality? Incidence, Simplex, and Product-Rule Tests in Finite Quantum Logics
Karl Svozil
The paper studies how finite quantum‑logical structures can be classified as classical or nonclassical using incidence, simplex‑embedding, and product‑rule tests, and calculates st…
Operational Shadows of Hilbert-Space Probabilities
Karl Svozil
At one frozen setting, the probabilities observed in a sharp quantum context are indistinguishable, as detector-click statistics, from ordinary probabilities on the atoms of a clas…
Chromatic Completeness and the Independence of Geometric Obstruction
Karl Svozil
We establish a strict logical separation between two distinct phenomena in orthogonality hypergraphs: chromatic completeness, the possibility of assigning a single globally consist…
Faithful real embedding of a three-dimensional complex Kochen-Specker configuration
Andrei Khrennikov, Karl Svozil
We describe a phase-adjusted realification procedure that embeds any finite set of rays in C^3 into R^6. By assigning an appropriate phase to each ray before applying the standard…
From Unitarity to Irreversibility: The Role of Infinite Tensor Products and Nested Wigner's Friends
Karl Svozil
The transition from unitary, reversible von Neumann-Everett quantum processes to non-unitary, irreversible processes and measurements is explored through infinite tensor products i…
