We're excited to share the Lean FRO Year 3 Roadmap today! It builds on work completed in the first two years of Lean FRO operations and will guide all #LeanLang development through July 2026.

In June 2024, during the “Prospects of Formal Mathematics” trimester in Bonn, a coffee-room chat with Johan Commelin ☕️ turned into an idea:

formalizing higher categorical concepts is hard, so there really should be a conference about it! 🚀

Like philosophy. But with more squiggles and fewer orphans on trains heading off a cliff. #formalmathematics #fuckthis

Apparently, the words that I use don't mean what they really mean. #formalmathematics

2. Subset: math concepts in proof assistants

See how subset can be modeled completely in proof assistant Lean and Turn-lang

1. Set: math concepts in proof assistants

See how Set can be modeled completely in proof assistant Lean and Turn-lang

See how challenging concepts like Partition, Equivalence Classes are modeled intuitively.

Watch me formalize Function related concepts in abstract algebra using turn-lang.
