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:[1]

Ki(X)𝐐=0, i>0.

It is named after Aleksei Nikolaevich Parshin and Alexander Beilinson.

Finite fields

The conjecture holds if dim X=0 by Quillen's computation of the K-groups of finite fields,[2] showing in particular that they are finite groups.

Curves

The conjecture holds if dim X=1 by the proof of Corollary 3.2.3 of Harder.[3] Additionally, by Quillen's finite generation result[4] (proving the Bass conjecture for the K-groups in this case) it follows that the K-groups are finite if dim X=1.
