**[Theme]** In a course of mathematical logic, a student performs pen-and-paper formal proofs by means of logical derivations. How does a student know that her formal proof is correct? complete? Alternatively, she can use a software/tool such as a proof assistant. The advantage of using a proof assistant in the class is to, first, check the correctness of a proof, and, second, assist the student in writing a formal proof where no step is omitted, the logic is explicit and the proof method is clearly stated.

**[Objective]** In this class, we:

- learn how to write formal proofs using the proof assistant Isabelle/HOL (https://isabelle.in.tum.de/).
- study and practice various proving techniques (e.g. natural deduction, induction, etc.).
