PROFILE
Jeremy Lindsay
Worked on the HEPLean/PhysLean repository to enhance the mathematical foundations of Lorentz group formalization in Lean. Delivered features establishing the equivalence between the restricted Lorentz group and the identity component, introduced generalized boosts, and updated Minkowski product definitions. Refactored and reorganized Lorentz-related modules, standardized naming conventions, and improved documentation to support maintainability and onboarding. Leveraged skills in abstract algebra, group theory, and formal verification to provide rigorous mathematical proofs and ensure theoretical correctness. The work focused on code clarity and extensibility, laying a robust groundwork for future physics-mathematics integrations and more advanced computations within the Lean ecosystem.

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.

Apr 1, 2025April 2025 (HEPLean/PhysLean) delivered: documentation enhancements for index notation and Lorentz resources; code refactors to remove erwt usage across LinearMaps.lean, Lorentz folder, and PauliMatrices module; introduction and normalization of the Restricted Lorentz group with proofs of closure, inverse, and normality; plus a fix for a broken dead Lorentz reference link. These changes improve maintainability, onboarding, and provide a solid mathematical foundation for future physics-math work.
