Today at Freie Universität BerLean there was a meeting to discuss what the definition of a polytope should be. Partial consensus was reached! This is of course about the long missing formalisation of polytopes in #lean4 and #mathlib, which
As a step towards computer-formalizing the classification of low-dimensional Lie algebras, we finally formalized our first non-boring theorem in #Lean4 ! If L is a 3-dimensional Lie algebra (over any field) with a one-dimensional commutator
Scott Armstrong (@scottnarmstrong) 긴 PDE·확률론 논문과 mathlib에 없는 다수의 전제까지 24~48시간 내 형식화할 수 있을 정도로 자동 정형화가 쉬워졌다고 주장하며, 이를 수행하는 방법을 블로그 글로 설명했다. Lean/mathlib 기반 수학 증명 자동화의 생산성 향상 신호다. https://x.com/scottnarmstrong/status/2106855895493685385 #auto
What “mathlib” means
WikipediaLean is a proof assistant and a functional programming language. It is based on the calculus of constructions with inductive types, the foundational type theory developed with the Coq theorem prover, which was renamed to Rocq in 2024. It is a free and open-source software project hosted on GitHub. Development is currently supported by the nonprofit Lean Focused Research Organization (FRO).

every network with a public tag surfaceFollow #mathlib straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/mathlib
