Abstract

We show that the higher Chow groups with modulus of Binda–Kerz–Saito for a smooth quasi-projective scheme $X$ is a module over the Chow ring of $X$. From this, we deduce certain pull-backs, the projective bundle formula, and the blow-up formula for higher Chow groups with modulus.

We prove vanishing of $0$-cycles of higher Chow groups with modulus on various affine varieties of dimension at least two. This shows in particular that the multivariate analogue of Bloch–Esnault–Rülling computations of additive higher Chow groups of $0$-cycles vanishes.
