Contributed foundational algebraic structures to the leanprover-community/mathlib4 repository, focusing on formalizing advanced concepts in abstract algebra using Lean. Developed a cocommutative bialgebra structure for SymmetricAlgebra, aligning its design with existing MonoidAlgebra patterns to ensure consistency and maintainability. Expanded the Hopf algebra framework by implementing a constructor based on convolution inverses and formalizing the convolution algebra for linear maps, clarifying antipode behavior and supporting commutative cases. Introduced quotient constructions for coalgebras, bialgebras, and Hopf algebras, enabling modular abstractions and safer reuse. Work emphasized mathematical rigor, formal verification, and collaboration within the theoretical computer science community.
