Online reading group "Intersection theory on stacks" Using the machinery of cones, we will define the intersection product of a scheme and a variety. Passing through rational invariance, this defines so-called refined Gysin homomorphisms, acting on Chow groups, representing intersection with some fixed subscheme. These generalise constructions seen in previous talks, and we will see that they satisfy many nice properties.
