Logarithmic Chow theory
arXiv:1810.03746
Abstract
We describe a refined Chow theory for log schemes extending the theory of b-Chow suggested Holmes Pixton and Schmidt based off of a definition of Shokurov. This produces a dimension graded family of Abelian groups supporting a push-forward and pull-back along proper and log flat morphisms respectively, together with a bivariant theory satisfying Poincare Duality. In the final section we relate this construction to the construction of the log normal cone by Leo Herr.
