Abstract

We construct some analog of cubical Bloch's higher Chow groups. Instead of considering cycles in X×AnX\times\mathbb A^n we consider varieties YY over XX together with a distinguished element in the nn-th exterior power of the multiplicative group of the field of fraction on YY. This definition allows us to make sense of a cycle in X×AnX\times\mathbb A^n intersecting faces improperly as an element in this complex. We prove that this complex is well-defined and study its basic properties: flat pullback, the localization sequence etc. As an application we prove that the cohomology of this complex in degrees m1,mm-1, m and weight mm isomorphic to the cohomology of polylogarithmic complex.
