Title: Excess Intersections
Abstract: I'll start off with a reminder of how the intersection product works on the Chow ring of a (smooth, projective) variety. Computing intersections of subvarieties with this product usually requires verifying some sort of transversality property. In real life, though, subvarieties aren't always transverse. I'll discuss what we can still conclude. For example, the excess intersection formula expresses the intersection of two subvarieties in terms of both their Chow classes and other terms involving their normal bundles.
