PROFILE
Jeremy Lindsay
Jeremy Lindsay contributed foundational mathematical features to the HEPLean/PhysLean repository, focusing on formalizing and refactoring core components of the Lorentz group in Lean. He introduced and normalized the restricted Lorentz group, establishing its equivalence to the identity component, and provided rigorous proofs of closure, inverse, and normality. His work included reorganizing Lorentz-related modules, updating Minkowski product definitions, and standardizing naming conventions to improve maintainability and clarity. Leveraging skills in abstract algebra, group theory, and formal verification, Jeremy’s contributions enhanced the theoretical soundness and extensibility of the codebase, laying groundwork for future developments in mathematical physics formalization.

Jun 1, 2025In 2025-06, delivered a core mathematical feature for HEPLean/PhysLean: establishing that the restricted Lorentz group is equivalent to the identity component. This work involved refactoring and reorganizing Lorentz-related modules, introducing generalized boosts, updating Minkowski product definitions, and standardizing file/lemma naming for consistency. All changes were committed in 6ddb4b1d632fca0c31ddd0e20c08141eb920e310 with a clear feature-focused message. No critical bugs were reported this month. Overall, the work strengthens the theoretical correctness of the Lorentz module, improves maintainability and readability, and lays the groundwork for future extensions and more robust physics computations.
