* Isabelle.

Isabelle is a generic proof assistant.

It allows mathematical formulas to be expressed in a formal language and

provides tools for proving those formulas in a logical calculus. The main

application is the formalization of mathematical proofs and in particular

formal verification, which includes proving the correctness of computer

hardware or software and proving properties of computer languages and

protocols.

* IsarMathLib.

This site is an experimental HTML rendering of fragments of the IsarMathLib

project. IsarMathLib is a library of mathematical proofs formally verified by

the Isabelle theorem proving environment. The formalization is based on the

Zermelo-Fraenkel set theory.
