WebAug 2, 2024 · It is easy to show, using representability of the Hilbert functor when $X\to S$ is projective, that the following holds: Theorem 2. Let $S$ be a scheme of pure … A more sophisticated solution to the problem of 'correctly' counting the degree of a degenerate subvariety is to work with subschemes of rather than subvarieties. Schemes can keep track of infinitesimal information that varieties and algebraic cycles cannot. For example, if two points in a variety approach each other in an algebraic family, the limiting subvariety is a single point, the limiting algebraic cycle is a point with multiplicity 2, and the limiti…
