  • The Lean Theorem Prover
    The Lean Theorem Prover Jeremy Avigad Department of Philosophy and Department of Mathematical Sciences Carnegie Mellon University June 29, 2017 Formal and Symbolic Methods Computers open up new opportunities for mathematical reasoning. Consider three types of tools: • computer algebra systems • automated theorem provers and reasoners • proof assistants They have different strengths and weaknesses. Computer Algebra Systems Computer algebra systems are widely used. Strengths: • They are easy to use. • They are useful. • They provide instant gratification. • They support interactive use, exploration. • They are programmable and extensible. Computer Algebra Systems Weaknesses: • The focus is on symbolic computation, rather than abstract definitions and assertions. • They are not designed for reasoning or search. • The semantics is murky. • They are sometimes inconsistent. Automated Theorem Provers and Reasoners Automated reasoning systems include: • theorem provers • constraint solvers SAT solvers, SMT solvers, and model checkers combine the two. Strengths: • They provide powerful search mechanisms. • They offer bush-button automation. Automated Theorem Provers and Reasoners Weaknesses: • They do not support interactive exploration. • Domain general automation often needs user guidance. • SAT solvers and SMT solvers work with less expressive languages. Ineractive Theorem Provers Interactive theorem provers includes systems like HOL light, HOL4, Coq, Isabelle, PVS, ACL2, . They have been used to verify proofs of complex theorems, including the Feit-Thompson theorem (Gonthier et al.) and the Kepler conjecture (Hales et al.). Strengths: • The results scale. • They come with a precise semantics. • Results are fully verified. Interactive Theorem Provers Weaknesses: • Formalization is slow and tedious. • It requires a high degree of commitment and experise. • It doesn’t promote exploration and discovery.

  • Downloading​ ​And​ ​Configuring​ ​Atom:​ ​A​ ​Beginner's​ ​Guide
    Downloading and Configuring Atom: A Beginner’s Guide ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Atom is a text editor with support for a number of programming and markup languages, including XML. It is free and open source. Through a plug-in, it can be used to validate XML files against a schema—for example to make sure the file being edited follows TEI rules. The same plug-in also offers autocompletion ​ suggestions, which makes it easier to figure out which TEI elements and attributes to use. ​ ​ ​ ​ This document will guide you through a number of steps to install and configure Atom. 1. Download Atom ​ ​ ​ ​ Atom can be downloaded at https://atom.io/. Versions are available for Windows, ​ ​ ​ ​ ​ ​ ​ ​ ​ ​​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Mac, and Linux. Select and install the appropriate version for your operating ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ platform, as you would any other application. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2. Install Java Development Kit (JDK) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The plug-in to validate XML requires Java code, a very common programming ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ language. The JDK can be downloaded here: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ http://www.oracle.com/technetwork/java/javase/downloads/jdk9-downloads-3848 520.html.

  • Elaboration in Dependent Type Theory
    Elaboration in Dependent Type Theory Leonardo de Moura, Jeremy Avigad, Soonho Kong, and Cody Roux∗ December 18, 2015 Abstract To be usable in practice, interactive theorem provers need to pro- vide convenient and efficient means of writing expressions, definitions, and proofs. This involves inferring information that is often left implicit in an ordinary mathematical text, and resolving ambiguities in mathemat- ical expressions. We refer to the process of passing from a quasi-formal and partially-specified expression to a completely precise formal one as elaboration. We describe an elaboration algorithm for dependent type theory that has been implemented in the Lean theorem prover. Lean’s elaborator supports higher-order unification, type class inference, ad hoc overloading, insertion of coercions, the use of tactics, and the computa- tional reduction of terms. The interactions between these components are subtle and complex, and the elaboration algorithm has been carefully de- signed to balance efficiency and usability. We describe the central design goals, and the means by which they are achieved. 1 Introduction Just as programming languages run the spectrum from untyped languages like Lisp to strongly-typed functional programming languages like Haskell and ML, foundational systems for mathematics exhibit a range of diversity, from the untyped language of set theory to simple type theory and various versions of arXiv:1505.04324v2 [cs.LO] 17 Dec 2015 dependent type theory. Having a strongly typed language allows the user to convey the intent of an expression more compactly and efficiently, since a good deal of information can be inferred from type constraints. Moreover, a type discipline catches routine errors quickly and flags them in informative ways.

This protocol can then be automatically translated to system that is significantly verified and performant, detailing equivalent code in a functional language and deployed using the design, proof, and system development based on a process of a shim layer to a network to obtain working reference imple- continuous refinement.
