Geometrical representation theorems for cylindric-type algebras
Mohamed Khaled, Tarek Sayed Ahmed · Quaestiones Mathematicae · 2019
In this paper, we give new proofs of the celebrated Andréka-Resek-Thompson representability results of certain axiomatized cylindric-like algebras. Such representability results provide completeness theorems for variants of first order logic, that can also be viewed as multi-modal logics. The proofs herein are combinatorial and we also use some techniques from game theory.
