Module aim (aims)

The aim of the course is to acknowledge the listener with the main tools of structural proof theory. The course is a concise introduction to structural proof theory: its origins, its main tools, and the consequences of the famous admissibility results (cut elimination). The focus is on sequent calculi for classical, intuitionistic, and minimal logic; however, natural deduction basics are also introduced. An emphasis is placed also on the techniques of proving cut elimination.

Pre-requisites in terms of knowledge, skills and social competences (where relevant)

Basic knowledge of classical logic: both propositional and first-order.
