We investigate uniform interpolants in propositional modal logics from the proof-theoretical point of view. Our approach is adopted from Pitts' proof of uniform interpolation in intuitionistic ...

The course begins with a simple system called sentential or propositional logic, which despite its simplicity captures a significant range of important arguments. The course then focuses on ...

Special attention is paid to the most basic logic in this hierarchy, the pure "intelim logic", which satisfies all the requirements of a natural deduction system (allowing both introduction and ...
