Projections for infinitary rewriting
Proof terms in term rewriting are a representation means for reduction sequences, and more in general for contraction activity, allowing to distinguish e.g simultaneous from sequential reduction.

Categoricity and infinitary logics
We point out a gap in Shelah's proof of the following result: $\mathbf{Claim}$ Let $K$ be an abstract elementary class categorical in unboundedly many cardinals. Then there exists a cardinal $ $ such that whenever $M, N \in K$ have size at least $ $, $M \le N$ if and only if $M \preceq_{L_{\infty, \text{LS} (K)^+}} N$.

Abstract A popular and enduring approach to the liar paradox takes the concept of truth to be inconsistent. Very roughly, truth is an inconsistent concept if the central principles of this concept (taken together) entail a contradiction, where one of these central principles is Tarski's T‐schema for truth: a sentence S is true if and only if p, (where ...

Abstract The idea that some objects are metaphysically “cheap” has wide appeal. An influential version of the idea builds on abstractionist views in the philosophy of mathematics, on which numbers and other mathematical objects are abstracted from other phenomena.

Abstract We provide two proofs of the compactness theorem for extensions of first‐order logic based on team semantics. First, we build upon Lück's [16] ultraproduct construction for team semantics and prove a suitable version of Łoś' Theorem. Second, we show that by working with suitably saturated models, we can generalize the proof of Kontinen and ...

Rule‐Following II: Recent Work and New Puzzles
Abstract “Rule‐following” is a name for a cluster of phenomena where we seem both guided and “normatively” constrained by something general in performing particular actions. Understanding the phenomenon is important because of its connection to meaning, representation, and content.

Abstract Quantifiers frequently figure in works of fiction. But occurrences of quantificational expressions within fictions seem no more inevitably to be associated with real domains than uses of names within fictions seem inevitably to be associated with existing referents.

Formal model theory and higher topology
Abstract We study the 2‐categories BIon, of (generalized) bounded ionads, and Accω$\text{Acc}_\omega$, of accessible categories with directed colimits, as an abstract framework to approach formal model theory. We relate them to topoi and (lex) geometric sketches, which serve as categorical specifications of geometric theories. We provide reconstruction
