Counterexample to the Jacobian Conjecture AF Ramos et al The conjecture asks whether a polynomial self-map of affine space has a polynomial inverse whenever its Jacobian determinant is a nonzero constant. This entry gives an Isabelle/HOL verification of the 3-d map announced by Levent Alpöge.

Anyone asking themselves "if AI can disprove the Jacobian conjecture, what's left for me to do?" ask yourself instead: "Which of yesterday's insurmountable problems might we solve today, with such tools at our command?" The superintelligence is *you* augmented with AI.

I've very fond memories of this game. But had you asked me to recall the graphics yesterday, I wouldn't have remembered it being this pixelated. Memory seems akin to a generative AI model. Hence the rose tinted glasses of nostalgia, as well as memory's fallibility. The past as mere hallucination.

To a layman’s definition of intelligence, the claim of frontier models being “PhD-level” has moved quickly from being farcical to arguable. We need to have our eyes open to the implications, not least for our PhD students and the future of research theconversation.com/a-phd-is-an-...
