Project description
Proof assistant advances could boost computer algebra reliability
Using computers to formulate conjectures and consolidate proof steps pervades all mathematics fields, even the most abstract. Most computer proofs are produced by symbolic computations, using computer algebra systems. However, these systems suffer from severe, intrinsic flaws, rendering computational correction and verification challenging. The EU-funded FRESCO project aims to shed light on whether computer algebra could be both reliable and fast. Researchers will disrupt the architecture of proof assistants, which serve as the best tools for representing mathematics in silico, enriching their programming features while preserving their compatibility with their logical foundations. They will also design novel mathematical software that should feature a high-level, performance-oriented programming environment for writing efficient code to boost computational mathematics.
Objective
The use of computers for formulating conjectures, but also for substantiating proof steps, pervades mathematics, even in its most abstract fields. Most computer proofs are produced by symbolic computations, using computer algebra systems. Sadly, these systems suffer from severe, intrinsic flaws, key to their amazing efficiency, but preventing any flavor of post-hoc verification.
But can computer algebra become reliable while remaining fast? Bringing a positive answer to this question represents an outstanding scientific challenge per se, which this project aims at solving.
Our starting point is that interactive theorem provers are the best tools for representing mathematics in silico. But we intend to disrupt their architecture, shaped by decades of applications in computer science, so as to dramatically enrich their programming features, while remaining compatible with their logical foundations.
We will then design a novel generation of mathematical software, based on the firm grounds of modern programming language theory. This environment will feature a new, high-level, performance-oriented programming language, devised for writing efficient and correct code easily, and for serving the frontline of research in computational mathematics. Users will have access to fast implementations, and to powerful proving technologies for verifying any component à la carte, with high productivity. Logic- and computer-based formal proofs will prevent run-time errors, and incorrect mathematical semantics.
We will maintain a close, continuous collaboration with interested high-profile mathematicians, on the verification of cutting-edge research results, today beyond the reach of formal proofs. We ambition to empower mathematical journals to install high-quality artifact evaluation, when peer-reviewing falls short of assessing computer proofs. This project will eventually impact the use of formal methods in engineering, in areas like cryptography or signal-processing.
