An upper bound for the Tarski numbers of nonamenable groups of piecewise projective homeomorphisms [PDF]

International journal of algebra and computation, 2016
The Tarski number of a non amenable group is the smallest number of pieces needed for a paradoxical decomposition of the group. Non amenable groups of piecewise projective homeomorphisms were introduced by Monod, and non amenable finitely presented ...

The I in logic

Theoria, EarlyView.
Abstract This paper argues for the significance of Kaplan's logic LD in two ways: first, by looking at how logic got along before we had LD, and second, by using it to bring out the similarity between David Hume's thesis that one cannot deduce claims about the future on the basis of premises only about the past, and the so‐called "essentiality" of the ...

Constant power maps on Hardy fields and transseries

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract Let T$\mathbb {T}$ be the differential field of logarithmic‐exponential transseries. We consider the expansion of T$\mathbb {T}$ by the binary map that sends a positive transseries f$f$ and a real number r$r$ to the transseries fr$f^r$, together with a constant symbol for the real number e$\mathrm{e}$. Building on recent work of Aschenbrenner,

Prawda: własność czy relacja?

Studia Philosophica Wratislaviensia
The starting point of the article is a passage in Tarski’s work entitled The Semantic Concept of Truth and the Foundations of Semantics (1944), in which he points out the difference between the concept of truth and other semantic concepts.

Czy Alfred Tarski jest relatywistą aletycznym? [Is Alfred Tarski Alethic Relativist?] [PDF]

Analiza i Egzystencja, 2013
In the article "Popper, Tarski and Relativism" Jennings argues that according to T-equivalence all ontology (all sort of things in the world) is the derived from the first-order language.

Weak, Strong and Mixed Extensions of Relations to Spaces of Ultrafilters

Mathematical Logic Quarterly, Volume 72, Issue 3, August 2026.
ABSTRACT The use of nonstandard methods to characterize properties of weak, strong and mixed extensions of congruences to ultrafilters has been the main topic of several recent papers, focused mostly on congruences and divisions. We show that similar methods can be used to extend these characterizations to arbitrary relations and their interplay.

Endogenous Distress Contagion in a Dynamic Interbank Model: How Possible Future Losses May Spell Doom Today

Mathematical Finance, Volume 36, Issue 3, Page 595-619, July 2026.
ABSTRACT We introduce a dynamic and stochastic interbank model with an endogenous notion of distress contagion, arising from rational worries about future defaults and ensuing losses. This entails a mark‐to‐market valuation adjustment for interbank claims, leading to a forward‐backward approach to the equilibrium dynamics whereby future default ...
