Bloch–Kato conjecture on integral motivic cohomology

Let UU be a smooth variety over a number field or a local field FF, and let \HMi(U,n)\HM^i(U,n) be its motivic cohomology. Let \HMfi(U,n)\HMf^i(U,n) be the subgroup whose \ell-adic Abel–Jacobi images lie in the Bloch–Kato finite subspaces Hf1(Fv,V)H^1_f(F_v,V_\ell) at every place vv and prime \ell, and let \HMOi(U,n)\HMO^i(U,n) denote the subgroup defined by the integral condition. Bloch–Kato's integrality conjecture.

\HMfi(U,n)=\HMOi(U,n).\HMf^i(U,n)=\HMO^i(U,n).

For fixed vv, the subspace

ker[\HMi(U,n)H1(Fv,V)/Hf1(Fv,V)]\ker\left[\HM^i(U,n)\to H^1(F_v,V_\ell)/H^1_f(F_v,V_\ell)\right]

is independent of \ell. This is presented as part of the generalisation of the Beilinson conjectures; the source gives no resolution status.
