In mathematics, the Goncharov conjecture is a conjecture introduced by Goncharov (1995) suggesting that the cohomology of certain motivic complexes coincides with pieces of K-groups. It extends a conjecture due to Zagier (1991).

Statement edit

Let F be a field. Goncharov defined the following complex called   placed in degrees  :

 

He conjectured that i-th cohomology of this complex is isomorphic to the motivic cohomology group  .
