Torsion conjecture for Chern classes of flat bundles of geometric origin
Torsion conjecture for Chern classes of flat bundles of geometric origin
Let be a smooth complex quasi-projective variety and let be a local system of geometric origin on . Let be the associated algebraic flat vector bundle. Geometric-origin torsion conjecture. All Chern classes of are torsion in the Chow ring:
This is presented as a strengthening of Esnault's conjecture on Chern classes of Gauss–Manin connections and would imply the properly rigid case assuming Simpson's geometric-origin conjecture. It remains open in general.
