Publications and Preprints

In reverse chronological order by posting date on arXiv or Zenodo. Related versions retain their shared publication number.

arXiv now limits each author to two new submissions per month. This limit would have been too strict for me much of the time even before AI, and recently too many arXiv submissions have been put on hold. For these reasons I am trying to post some of my papers on Zenodo.

2026

77. A counterexample to the Popa–Schnell global generation conjecture

Zenodo:23334837

75. Spectral gap, internality of relative commutants, and non-hyperlinear groups

arXiv:2609.37761

74. The minimal volume of normal stable surface pairs with reduced boundary containing a zero-dimensional non-klt center

arXiv:2609.27259

73. Embedded constant mean curvature tori in hemispheres of Berger spheres

arXiv:2609.23484

72. Disproof of the Yau–Tian–Donaldson conjecture

Note. For general polarized varieties, this disproves Donaldson’s 2002 cscK YTD conjecture even after the standard modern repairs to test configurations (normality and the product-in-codimension-two equality convention). The (log) Fano Kähler–Einstein YTD theorem and recent uniform/completed cscK YTD results are unaffected.
