Finite models for positive combinatorial and exponential algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3380-3400, November 2025.Abstract We use high girth, high chromatic number hypergraphs to show that there are finite models of the equational theory of the semiring of non‐negative integers whose equational theory has no finite axiomatisation, and show this also holds if factorial, fixed base exponentiation and operations for binomial coefficients are adjoined.

, 2011 In the present work we study the Banach-Tarski Paradox and other paradoxical decompositions of sets, groups and semigroups. These decompositions are described especially using free groups and semigroups.

Existence of a non‐stationary equilibrium in search‐and‐matching models: TU and NTU
Theoretical Economics, Volume 20, Issue 4, Page 1411-1460, November 2025.This paper proves the existence of a non‐stationary equilibrium in the canonical search‐and‐matching model with heterogeneous agents. Non‐stationarity entails that the number and characteristics of unmatched agents evolve endogenously over time.

Is Kant's critique of metaphysics obsolete?
Philosophy and Phenomenological Research, Volume 111, Issue 1, Page 25-53, July 2025.Abstract I raise a problem about the possibility of metaphysics originally due to Kant: what explains the fact that the terms in our metaphysical theories (e.g., ‘property’, ‘grounding’) refer to entities and structures (e.g., properties, grounding) in the world?

THE BANACH-TARSKI PARADOX [PDF]
, 2020 . This paper is an exposition of the Banach-Tarski paradox. We will first simplify the theorem by duplicating almost every point in the ball, and then extend our proof to the whole ...

Philosophy and Phenomenological Research, Volume 111, Issue 1, Page 71-86, July 2025.Abstract Contemporary ontologists, almost unanimously, dismiss the idea that sakes (as in ‘I did it for her sake’) exist. Likewise with the kibosh, snooks, behalves, dints, and so on. In this essay, I argue that there is no good reason for this near consensus, I begin to make a case that sakes and the like do exist, and I consider what this means more ...

Legal Systems and Complexity: A Comment on Allen
Ratio Juris, Volume 38, Issue 2, Page 94-107, July 2025.Abstract This work addresses Ronald J. Allen's views on complexity, evidence, and law. After some remarks on normative systems and the metaphors used to characterize them, the work addresses the issue of complexity by asking how a system characterized by complexity can tame the world's complexity; the focus then shifts to some aspects of evidence and ...

Gödel, Tarski, Church, and The Liar [PDF]
Bulletin of Symbolic Logic, 2003 The fact that Gödel's famous incompleteness theorem and the archetype of all logical paradoxes, that of the Liar, are related closely is, of course, not only well known, but is a part of the common knowledge of the community of logicians. Indeed, almost every more or less formal treatment of the theorem makes a reference to this connection.
