LISA (LISA Is Sets Automated) is a proof assistant based on first-order logic sequent calculus and set theory.
It provides a trusted kernel for checking proofs, together with a domain-specific language and supporting utilities for developing formal proofs, tactics, and mathematical theories.
This is free and open source software.
Key Features
- Based on first-order logic, sequent calculus, and set theory.
- Trusted kernel verifies all accepted theorems and proofs.
- Formalisation of first-order logic.
- Proofs formalised through sequent calculus.
- Domain-specific language for writing proofs and mathematical developments.
- Supports development of proof tactics.
- Parser and printer for proofs and formulas.
- Provides unification algorithms.
- Includes a mathematical library with set theory developments.
