Modular proof analysis and cut elimination for the Reflection Calculi $RC_{1}$ and $QRC_{1}$

Joost J. Joosten, Cosimo Perini Brogi

The reflection calculus with one modality is denoted by $RC_{1}$ and its quantified generalization is known as $QRC_{1}$ . These decidable calculi are of interest sinc…

Ultrafilter Extensions for Veltman Semantics

Fèlix Frigola González, Joost J. Joosten, Vicent Navarro Arroyo +1

In this paper, we present a first-order frame condition for interpretability logic and show that the condition is not modally definable. Yet, the frame condition holds both on ILM…
