Abstract

We prove the Parshin's conjecture on the rational triviality of the higher algebraic KK-theory of smooth projective varieties over finite fields. This is known to imply the Beilinson-Soul\'e conjecture for the fields of positive characteristic. Especially it implies that for a field FF of char pp and n>0n>0, the only rationally non-trivial weight appearing in Kn(F)QK_n(F)\otimes \mathbb{Q} can be nn, thus Kn(F)Q=KnM(F)QK_n(F)\otimes \mathbb{Q}=K_n^M(F)\otimes \mathbb{Q} where KnM(F)K_n^M(F) is the Milnor KK-theory.

11 pages. Comments are welcome. There is a problem with the Theorem 4.7. Which could be fixed by taking double duals (category of reflexive sheaves) but it ruins the double deformation construction
