Ramachandran's Bochner–Hartogs or surface-group dichotomy
Ramachandran's Bochner–Hartogs or surface-group dichotomy
Let be a smooth projective variety with a type B Zariski-dense representation to a Lie group defined over a local field , and set . Assume that is finite. The Bochner–Hartogs property for means that for every compactly supported -form with , there is a compactly supported smooth function such that .
Ramachandran's conjecture. One of the following holds: the universal cover has the Bochner–Hartogs property, or is commensurable with the fundamental group of a compact Riemann surface.
The paper attributes this question to M. Ramachandran and presents it as a possible application of the Shafarevich–Kollár conjecture. The supplied text gives no resolution status.
