Simplicity of the Hodge Bundle

Precise statement

Does the Hodge bundle $\Omega_g$ over the moduli stack of genus $g \ge 2$ curves contain any nontrivial sub-bundles? Posed by Dawei Chen around 2015; the answer is no.

The source statement is reproduced for indexing with attribution. Mathematical correctness requires domain-expert or mechanical review. VibeMath has not independently audited statement fidelity, correctness, priority, or novelty.
