Claude used my pipeline to find a counterexample to the Jacobian conjecture

Hacker News - Fri, 07/24/2026 - 8:05pm

About a month ago, I released under CC0 an implementation of a pipeline I had spent two years developing. It’s the pipeline Claude used to find the counterexample to the Jacobian conjecture. The repository history, public release, discussion with one of the original paper’s authors, and two years of development logs document the pipeline’s origin and development.

Proof - https://github.com/JGPTech/Fun/tree/main/Jacobian

The history:

I first released it under CC0 a little over a month ago. You can find the link here: https://github.com/JGPTech/Fun/commits/main/current_paper_locality_boundary_package

This is the paper I was modeling with this pipeline: https://www.nature.com/articles/s41467-026-73900-9

This is where I shared it publicly one of the paper’s authors, which you can see he approved of: https://www.linkedin.com/feed/update/urn:li:activity:7470810642321571840?commentUrn=urn%3Ali%3Acomment%3A%28activity%3A7470810642321571840%2C7471734053742895105%29&dashCommentUrn=urn%3Ali%3Afsd_comment%3A%287471734053742895105%2Curn%3Ali%3Aactivity%3A7470810642321571840%29

How cool is it that Claude used it on a problem this big, and that the mathematical community around this counterexample is now thinking through structures I spent years developing? What a ride.

Ask HN: How would I restore this 101 year old postcard?

Hacker News - Fri, 07/24/2026 - 7:48pm

How do I approach making this legible? Is there a “magical AI” solution these days? I know the basics of image processing and filtering but I can barely read my own handwriting so I suspect I’d need help from AI or someone even if I managed to isolate the signal.

P.S. I hope I’m not doxxing my great great grandfather or anything.
