Coq

Kleine Sammlung an Coq-Aufgaben zum Üben auf Einstiegsniveau.

This experimental project aims to build a proof assistant for propositional logic inside another proof assistant: Coq. The main idea is to implement natural deduction rules from the GLoIn-Lecture directly in Coq in order to have a suitable environment to prove stuff in Fitch-Style inside of Coq.

Implementation of PCF (inspired by lecture "Monad-Based Programming") in Coq

Formalization of numbers (Z,Q, ...), inspired by the lecture "Didaktik der Arithmetik"

An attempt at a Coq formalization of Zermelo-Fränkel set theory.
