In mathematics, more specifically in algebraic geometry, Parshin's conjecture (also referred to as the Beilinson–Parshin conjecture) states that for any smooth projective variety X defined over a finite field, the higher algebraic K-groups vanish up to torsion:

K i ( X ) Q = 0   i > 0.

It is named after Aleksei Nikolaevich Parshin and Alexander Beilinson.

Points and curves

The conjecture holds for a finite field by Quillen's computations of the K-groups in this case. Secondly, for a smooth proper curve, Quillen has shown that the K-groups are finitely generated, while Harder's computations show that the groups are torsion. The two results together thus show Parshin's conjecture for curves.
