Inadequacy of Modal Logic in Quantum Settings [PDF]
We test the principles of classical modal logic in fully quantum settings. Modal logic models our reasoning in multi-agent problems, and allows us to solve puzzles like the muddy children paradox.

A logic of separating modalities
AbstractWe present a logic of separating modalities, LSM, that is based on Boolean BI. LSM's modalities, which generalize those of S4, combine, within a quite general relational semantics, BI's resource semantics with modal accessibility. We provide a range of examples illustrating their use for modelling.

A system FP of propositional logic is maximal for the corresponding system FA of arithmetic if the underivability of \(A(p_ 1,...,p_ n)\) in FP implies underivability in FA of \(A(B_ 1,...,B_ n)\) for some sentences \(B_ 1,...,B_ n\) of FA. The authors prove maximality for Grzegorczyk's modal logic Grz and for S4.

Lindstrom theorems for fragments of first-order logic [PDF]
Lindstr\"om theorems characterize logics in terms of model-theoretic conditions such as Compactness and the L\"owenheim-Skolem property. Most existing characterizations of this kind concern extensions of first-order logic.

The modal logic of forcing [PDF]
A set theoretical assertionψ\psiisforceableorpossible, written◊ψ\Diamond \psi, ifψ\psiholds in some forcing extension, andnecessary, written◻ψ\Box \psi, ifψ\psiholds in all forcing extensions. In this forcing interpretation of modal logic, we establish that if ZFC is consistent, then the ZFC-provable principles of forcing are exactly those in the modal

A many-valued modal logic, called linear abelian modal logic \(\rm {\mathbf{LK(A)}}\) is introduced as an extension of the abelian modal logic \(\rm \mathbf{K(A)}\). Abelian modal logic \(\rm \mathbf{K(A)}\) is the minimal modal extension of the logic of

100 years ago C.I. Lewis published A Survey of Symbolic Logic, which included an axiom system for a notion of implication which was ‘stricter’ than that found in Whitehead and Russell’s Principia Mathematica.

This study explores combining two existing aerospace titanium alloy powders, processing them via field‐assisted sintering technology and the subsequent discovery of a novel alloy composition, termed S23, with ultra‐high tensile toughness. Fine‐scale alpha precipitates favorably form in the alloy despite the relatively slow cooling, providing an ...

AbstractTreating the existential quantification ∃νi as a diamond ♢i and the identity νi = νj as a constant δij, we study restricted versions of first order logic as if they were modal formalisms. This approach is closely related to algebraic logic, as the Kripke frames of our system have the type of the atom structures of cylindric algebras; the full ...
