* 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.

The goal of the project is to create a library of formalized mathematics,

similar to the Mizar Mathematical Library, but written for the Isabelle/Isar

theorem prover (ZF logic).

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.

* The TPTP Problem Library for Automated Theorem Proving.

The TPTP (Thousands of Problems for Theorem Provers) is a library of test

problems for automated theorem proving (ATP) systems. The TPTP supplies the

ATP community with:

 * A comprehensive library of the ATP test problems that are available today,

   in order to provide an overview and a simple, unambiguous reference

   mechanism.

 * A comprehensive list of references and other interesting information for

   each problem.

 * Arbitrary size instances of generic problems (e.g., the N-queens problem).

 * A utility to convert the problems to existing ATP systems' formats.

 * General guidelines outlining the requirements for ATP system evaluation.

 * Standards for input and output for ATP systems.

The principal motivation for the TPTP is to support the testing and evaluation

of ATP systems, to help ensure that performance results accurately reflect the

capabilities of the ATP system being considered. A common library of problems

is necessary for meaningful system evaluations, meaningful system comparisons,

repeatability of testing, and the production of statistically significant

results. The TPTP is such a library.

* Conference.

IJCAR is a series of conferences on the topics of automated reasoning,

automated deduction, and related fields. It is organized semi-regularly as a

merger of other meetings. IJCAR replaces those independent conferences in the

years it takes place. The conference is organized by CADE Inc., and CADE has

always been one of the conferences partaking in IJCAR.
