, 2015 In this paper we study fundamental model-theoretic questions for free associative algebras, namely, first-order classification, decidability of the first-order theory, and definability of the set of free bases.

THE TARSKI NUMBERS OF GROUPS [PDF]
, 2014 The Tarski number of a non-amenable group G is the minimal number of pieces in a paradoxical decomposition of G . In this paper we investigate how Tarski numbers may change under various group-theoretic operations.

Plank theorems and their applications: A survey
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract Plank problems concern the covering of convex bodies by planks in Euclidean space and are related to famous open problems in convex geometry. In this survey, we introduce plank problems and present surprising applications of plank theorems in various areas of mathematics.

Noûs, Volume 59, Issue 4, Page 851-872, December 2025.Abstract A new argument is offered which proceeds through epistemic possibility (for all S knows, p), cutting a trail from modality to Millianism, the controversial thesis that the semantic content of a proper name is simply its bearer. New definitions are provided for various epistemic modal notions.
