Encoding many-valued logic in $\lambda$-calculus [PDF]
We will extend the well-known Church encoding of Boolean logic into $\lambda$-calculus to an encoding of McCarthy's $3$-valued logic into a suitable infinitary extension of $\lambda$-calculus that identifies all unsolvables by $\bot$, where $\bot$ is a ...

The Topology-Free Construction of the Universal Type Structure for Conditional Probability Systems [PDF]
We construct the universal type structure for conditional probability systems without any topological assumption, namely a type structure that is terminal, belief-complete, and non-redundant.

Internalising modified realisability in constructive type theory [PDF]
A modified realisability interpretation of infinitary logic is formalised and proved sound in constructive type theory (CTT). The logic considered subsumes first order logic.

Infinitary Classical Logic: Recursive Equations and Interactive Semantics [PDF]
In this paper, we present an interactive semantics for derivations in an infinitary extension of classical logic. The formulas of our language are possibly infinitary trees labeled by propositional variables and logical connectives.

Coinductive Foundations of Infinitary Rewriting and Infinitary Equational Logic [PDF]
We present a coinductive framework for defining and reasoning about the infinitary analogues of equational logic and term rewriting in a uniform, coinductive way.

Finitary Simulation of Infinitary $\beta$-Reduction via Taylor Expansion, and Applications [PDF]
Originating in Girard's Linear logic, Ehrhard and Regnier's Taylor expansion of $\lambda$-terms has been broadly used as a tool to approximate the terms of several variants of the $\lambda$-calculus. Many results arise from a Commutation theorem relating

Quantifying over Boolean announcements [PDF]
Various extensions of public announcement logic have been proposed with quantification over announcements. The best-known extension is called arbitrary public announcement logic, APAL.

Circular Proofs as Session-Typed Processes: A Local Validity Condition [PDF]
Proof theory provides a foundation for studying and reasoning about programming languages, most directly based on the well-known Curry-Howard isomorphism between intuitionistic logic and the typed lambda-calculus.

Omitting Types in Fragments and Extensions of First Order Logic
Fix \(2 < n < \omega\). Let \(L_n\) denote first order logic restricted to the first n variables. Using the machinery of algebraic logic, positive and negative results on omitting types are obtained for \(L_n\) and for infinitary variants and extensions ...
