Assistant professor (of mathematics) at the University of Toronto, visiting Harvard Fall 2026. Forever confused. Algebraic geometry, number theory, etc. He/him.
One of the three withdrawn manuscripts was “Algebraicity of Kuga–Satake Correspondences for K3 Surfaces” which I had started trying to understand; it’s a question I quite like. The ideas seemed to be exciting, though of course this is no longer clear.
In cases like this with a human-authored manuscript, one can often still extract something interesting from the wrong argument (which is often still based on some perhaps-correct intuitions of the author). It’s less clear if that is possible here, and my experience is that AI is not as helpful for this kind of fuzzy task as one might hope.
