WebDec 24, 2007 · These relations suffice, as we shall demonstrate with a few examples, to write down enough relations in Bloch's integral higher Chow group CH^2 (F,3) for certain number fields F to detect torsion cycles. Using the regulator map to Deligne cohomology, one can check the non-triviality of the torsion cycles thus obtained.

"WebFor higher Chow complexes, a similar result was known by [Bloch, online note, Theorem 4.4.2] and such results help us in proving the moving lemma for higher Chow groups of smooth quasi-projective varieties as in [Bloch, 1994]. We hope Theorem 1.0.3 will lead us to an eventual resolution of Scholium 1.0.2 in the future. " - Bloch higher chow group

Some of the deepest conjectures in algebraic geometry and number theory are attempts to understand Chow groups. For example: • The Mordell–Weil theorem implies that the divisor class group CHn-1(X) is finitely generated for any variety X of dimension n over a number field. It is an open problem whether all Chow groups are finitely generated for every variety over a number field. The Bloch–Kato conjecture on values … WebThis problem was resolved by generalizing Chow groups to a bigraded family of groups, (Borel–Moore) motivic homology groups (which were first called higher Chow groups by Bloch). Namely, for every scheme X of finite type over a field k and integers i and j, we have an abelian group H i (X,Z(j)), with the usual Chow group being the special case
