Parshin's torsion conjecture for algebraic K-groups over finite fields

About 14 years old · traced to

Let kk be a finite field of characteristic p>0p>0, and let XX be a smooth projective variety over kk. For each integer n≥1n\geq 1, let Kn(X)K_n(X) denote the algebraic KK-group of XX. Parshin's conjecture. The group Kn(X)K_n(X) is torsion for all integers n≥1n\geq 1. This conjecture, together with Bass's finite generation conjecture, predicts the structure of algebraic KK-groups of smooth projective varieties over finite fields. It remains open in general, except when dim(X)≤1\text{\rm dim}(X)\leq 1.
