Tarski monoids: Matui's spatial realization theorem

open access: yes, 2017
We introduce a class of inverse monoids, called Tarski monoids, that can be regarded as non-commutative generalizations of the unique countable, atomless Boolean algebra. These inverse monoids are related to a class of etale topological groupoids under a

The First-Order Theory of Sets with Cardinality Constraints is Decidable

open access: yes, 2004
We show that the decidability of the first-order theory of the language that combines Boolean algebras of sets of uninterpreted elements with Presburger arithmetic operations. We thereby disprove a recent conjecture that this theory is undecidable.
