Topic: just saying hi

Hi! Cools stuff going on here, looking forward to learn from you.

Christian Schöner (Sep 22 2024 at 19:11):

Hi! I'm new here, too! Keep it up, good work!

Hi, I'm Adam. I've been working on formalizing quantum mechanics in Lean 4, specifically handling unbounded operators properly (Robertson uncertainty, Stone's theorem, spectral theory). I think this makes Lean the first theorem prover where you can actually do real QM, not just finite-dimensional toy models.

I'm currently working on Cayley transform before I move on to functional calculus for spectral theory.

Thanks for any scrutiny you can offer.

Hi @Adam Bornemann , you may be interested in the projects/channels #PhysLean and #Quantum information

Yoh Tanimoto (Jan 06 2026 at 14:22):

there is an ongoing work on the spectral theorem, see the discussion around
#mathlib4 > L^infty as C*-algebra @ 💬
I'm hoping to come back to work after the exams are done in february
