Qin's quasimodularity conjecture for Hilbert schemes of points
Victor Alekseev, Avik Chakravarty, Daebeom Choi +1
Let be a smooth projective complex surface with numerically trivial canonical class. With the help of GPT-5.6 Sol, we prove Qin's conjecture that the reduced generating series…

Counterexamples to Sato's Weak F-Equivalence Conjecture and a Gorenstein Refinement
Avik Chakravarty, Daebeom Choi, Daeboem Choi +1
We disprove Sato's weak \(F\)-equivalence conjecture for nonsingular projective toric weak Fano varieties in every dimension \(d \geq 3\). Our counterexamples are smooth projective…
