The Simplicity of the Hodge Bundle

Abstract

This paper shows that the Hodge bundle over the moduli space of genus $g\ge 2$ curves does not contain any non-trivial sub-bundles. Notably, the mathematical content was generated by Aletheia, a custom AI agent powered by Gemini Deep Think.

The human had dropped the 4 in Lemma 2.7 during re-write -- now it's been fixed. See Human Comment 2.8
