Project description
Advancing harmonic analysis with machine-verified solutions
Mathematics is becoming more reliable with the help of computers that can check whether complex proofs are correct. The ERC-funded HALF project will help tackle big problems in a field called harmonic analysis. Researchers will use a computer programme, Lean, to verify harmonic analysis solutions, with a focus on multilinear and non-linear operators. New tools and libraries will be developed to enhance Lean’s capabilities in this field. HALF is a pioneering step toward making computer verification routine in mathematical research. It also paves the way for computers and AI to play a bigger role in helping mathematicians discover and validate mathematical truths.
Objective
Recent advances in formalization have brought the longstanding vision of machine-verifiable mathematics within reach. Formed by world leading experts in harmonic analysis and formalization, HALF is the first research initiative to concurrently achieve breakthrough results in a foundational mathematical area while formalizing them in the proof assistant Lean.
HALF tackles pivotal and long-standing open problems in harmonic analysis, with an emphasis on multilinear and nonlinear operators. These fundamental questions are motivated intrinsically and also have applications in other mathematical and interdisciplinary fields such as ergodic theory and quantum computing. HALF also extends Lean's capabilities, establishing comprehensive libraries and tools tailored for the efficient formalization of harmonic analysis and related mathematical domains.
Being the first of its kind, HALF is a milestone towards making computer verification routine in research mathematics. It produces highly needed training material for anticipated artificial intelligence applications that will in the future aid the verification process and provide automated tools for rigorous discovery in mathematics.
