PROFILE
Duncan Lowther
Duncan Lowther contributed to the agda/agda-categories repository by enhancing the Bicategory Object Product and refactoring Product record encapsulation. He added a missing congruence and derived a proof of the defining equivalence on hom-categories, improving the formal correctness and extensibility of the codebase. His work involved privatizing certain modules, which strengthened the structure and maintainability of the Product record implementation. Using Agda and leveraging expertise in category theory, type theory, and formal verification, Duncan’s contributions addressed foundational aspects of the library, laying groundwork for future development and ensuring that the code remains robust and easier to extend or modify.
