Abstract: In this talk, we will discuss the experience of formalizing a classification theorem for solvable Lie algebras of dimension at most three in the Lean theorem prover. We will briefly introduce the mathematics required to understand the statement (no prior background in Lie theory will be assumed) and explain the motivation behind formalizing the result. We will outline the process of formalizing these results using mathlib (the unified mathematical library for Lean), and the challenges encountered along the way. Finally, we will conclude with an update on the current status of the project and what we expect to continue working on in the future.
