Abstract

We show that the multivariate additive higher Chow groups of a smooth affine -scheme essentially of finite type over a perfect field of characteristic form a differential graded module over the big de Rham–Witt complex ^bullet_R. In the univariate case, we show that additive higher Chow groups of form a Witt-complex over . We use these structures to prove an étale descent for multivariate additive higher Chow groups.
